# Eclipse Platform Build Notes
Java development tools core

Eclipse SDK 3.1RC2 - 9th June 2005
Project org.eclipse.jdt.core v_561 (cvs).

## What's new in this drop

- The build state version number has changed. A full build of all projects in the workspace will be triggered upon startup if autobuild is on, or on the next build if autobuild is off.
- The new list of supported warning tokens for the @SuppressWarnings annotation is:
  - all : any warning
  - boxing : autoboxing conversion
  - dep-ann : missing @Deprecated annotation
  - deprecation : deprecation outside deprecated code
  - incomplete-switch : incomplete enum switch (enumSwitch)
  - hiding :
    1. field hiding another variable (fieldHiding)
    2. local variable hiding another variable (localHiding)
    3. type parameter hiding another type (typeHiding)
    4. hidden catch block (maskedCatchBlock)
  - finally : finally block not completing normally
  - static-access :
    1. indirect reference to static member (indirectStatic)
    2. non-static reference to static member (staticReceiver)
  - nls : string literal lacking non-nls tag //$NON-NLS-<n>$
  - serial : missing serialVersionUID
  - unqualified-field-access : unqualified reference to field (unQualifiedField)
  - unchecked : unchecked type operation
  - unused :
    1. unread method parameter (unusedArgument)
    2. unread local variable (unusedLocal)
    3. unused private member declaration (unusedPrivate)
    4. unused declared thrown exception (unusedThrown)
  - synthetic-access : synthetic access for innerclass (syntheticAccess)

  NOTE:

  > All other warning tokens are not longer supported by @SuppressWarnings; considering that for some diagnosis, it is simpler to just fix the code than silence some warning. In Italic the old warning token is specified.
  > Warning tokens also supported by javac are in red (also see declared warning tokens).

- CodeAssist: added a new API CompletionProposal#isConstructor() to distinguish method and constructor proposal
- Access rules file patterns have been changed to ignore the file extension. This allow easy switching from a source project to a binary project. Thus `"com/test/X.java"` is now an invalid access rule pattern, and `"com/test/X"` is a valid access rule pattern.
- Following batch compiler options default value have been changed from "ignore" to "warning":
  - unusedLocal (unread local variable)
  - unusedPrivate (unused private member declaration)
  - fieldHiding (field hiding another variable)
  - localHiding (local variable hiding another variable)
  (see bug 76530)
- Compiler optional diagnosis for unused private members got generalized to also flag unused members of local types.
- Compiler no longer reports as unchecked the situation where a method of a raw type is invoked, and only the return type got altered by raw conversion (also see bug 85815). This change is motivated to better match the language spec 3rd edition.
- Fix for bug 97087 required the index version to be incremented. Indexes will be automatically regenerated upon subsequent search queries (accounting for indexing notification in search progress dialogs).

# Eclipse Platform Build Notes
Java development tools core

Eclipse SDK 3.1RC1 - 26th May 2005
Project org.eclipse.jdt.core v_558 (cvs).

## What's new in this drop

- The Code Assist option CODEASSIST_HIDE_RESTRICTED_REFERENCES is replaced by CODEASSIST_FORBIDDEN_REFERENCE_CHECK and CODEASSIST_DISCOURAGED_REFERENCE_CHECK (see bug 94403).
- Code Assist suggest all member types when completion token is a single name.

      Y<complete here> // p.q.X.Y is proposed.

  As all member types are proposed, code assist does not propose types of the wrong kind. Only classes are proposed inside an extends clause, only interfaces inside an implements clause and only annotations in annotation reference (It was necessary before to be able to propose a top level type which contains these types).
  Note: To re-enabled quickly the old behaviors, change the value of Completion.PROPOSE_MEMBER_TYPES.
- Added API `JavaCore#initializeAfterLoad(IProgressMonitor)` to allow a client to force the initialization of internal structures.
- Default value for `COMPILER_PB_MISSING_JAVADOC_COMMENTS_OVERRIDING` and `COMPILER_PB_MISSING_JAVADOC_TAGS_OVERRIDING` JavaCore options have been changed from "enabled" to "disabled".
  (see bug 96270).
- Fix for bug 75816 required the index version to be incremented. Indexes will be automatically regenerated upon subsequent search queries (accounting for indexing notification in search progress dialogs).
- Duplicate names are not allowed in classpath entry extra attributes.
  Javadoc comment of each `JavaCore.new*Entry` method have been updated to clearly specify this behavior:

       * The extraAttributes list contains name/value pairs that must be persisted with
       * this entry. If no extra attributes are provided, an empty array must be passed in.
       * Note that this list should not contain any duplicate name.

  `JavaConventions.validateClasspathEntry(IJavaProject,IClasspathEntry,boolean,boolean)` has been modified to verify this point. It now returns an invalid status (`new IJavaStatus(IJavaModelStatusConstants.NAME_COLLISION,...)`) when duplicate names are found in extra attributes.

94308 [1.5][compiler] @SuppressWarnings("deprecation") does not suppress warnings from javadoc

# Eclipse Platform Build Notes
Java development tools core

Eclipse SDK 3.1M7 - 12th May 2005
Project org.eclipse.jdt.core v_556 (cvs).

## What's new in this drop

- Enabled by default the optional compiler diagnosis to signal unhandled warning tokens in `@SuppressWarnings` annotations. Note that this warning can itself be turned off using @SuppressWarnings("warningToken").

      * COMPILER / Reporting Unhandled Warning Token for @SuppressWarnings
      *    When enabled, the compiler will issue an error or a warning when encountering a token
      *    it cannot handle inside a @SuppressWarnings annotation.
      *     - option id:         "org.eclipse.jdt.core.compiler.problem.unhandledWarningToken"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "warning"

- Fix for bug 94718 required the index version to be incremented. Indexes will be automatically regenerated upon subsequent search queries (accounting for indexing notification in search progress dialogs).

Project org.eclipse.jdt.core v_555 (cvs).

## What's new in this drop

- Code Assist provide the enclosing type reference when cursor is inside a type argument and the completion token is empty (in the same way as method calls).

      p.q.X<<complete here>> // p.q.X<T,U> is proposed.
      p.q.X<Object, <complete here>> //p.q.X<T,U> is proposed

- Code Assist provide the enclosing annotation reference when completion is inside an annotation argument and the completion token is empty (in the same way as method calls).

      @Annot(<complete here>) // p.Annot is proposed.
      @Annot(foo1=0, <complete here>) // p.Annot is proposed.

- In 5.0 compliant mode, changed local inner type naming convention to reflect JLS 13.1 (3rd edition). As a consequence, instead of generating a file named `X$1$A.class`, it will simply be `X$1A.class"`.
- Added optional compiler diagnosis to signal unhandled warning tokens in `@SuppressWarnings` annotations. Note that this warning can itself be turned off using @SuppressWarnings("warningToken").

      * COMPILER / Reporting Unhandled Warning Token for @SuppressWarnings
      *    When enabled, the compiler will issue an error or a warning when encountering a token
      *    it cannot handle inside a @SuppressWarnings annotation.
      *     - option id:         "org.eclipse.jdt.core.compiler.problem.unhandledWarningToken"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "ignore"

- Added compiler option to control whether @SuppressWarning annotations are active or not. By disabling them, one can quickly revive all hidden warnings.

      * COMPILER / Determine whether @SuppressWarnings is effective
      *    When enabled, the @SuppressWarnings annotation can be used to suppress some compiler warnings.
      *    When disabled, all @SupressWarnings annotations are ignored; i.e., warnings are reported.
      *     - option id:         "org.eclipse.jdt.core.compiler.problem.suppressWarnings"
      *     - possible values:   { "enabled", "disabled" }
      *     - default:           "enabled"

- Added API on `CorrectionEngine` for computing the warning token corresponding to an optional warning ID.

      /**
       * Returns a token which can be used to suppress a given warning using
       * @SuppressWarnings annotation, for a given problem ID
       * ({@link IProblem }). If a particular problem is not suppressable,
       * null will be returned.
       *
       * Note: @SuppressWarnings can only suppress warnings,
       * which means that if some problems got promoted to ERROR using custom compiler
       * settings ({@link IJavaProject#setOption(String, String)}), the
       * @SuppressWarnings annotation will be ineffective.
       *
       * Note: @SuppressWarnings can be argumented with
       * "all" so as to suppress all possible warnings at once.
       *
       * Note: The tokens returned are not necessarily standardized across Java
       * compilers. If you were to use one of these tokens in an @SuppressWarnings
       * annotation in the Java source code, the effects (if any) may vary from
       * compiler to compiler.
       *
       * @param problemID
       *         the ID of a given warning to suppress
       * @return a String which can be used in @SuppressWarnings annotation,
       * or null if unable to suppress this warning.
       * @since 3.1
       */
      public static String getWarningToken(int problemID)

- More warning tokens are now recognized by `@SuppressWarnings`, see list below. Note that these are subject to changing in the near future.
  - all : any warning
  - boxing : autoboxing conversion
  - charConcat : char[] in String concat
  - conditionAssign : possible accidental boolean assignment
  - constructorName : method with constructor name
  - dep-ann : missing @Deprecated annotation
  - deprecation : deprecation outside deprecated code
  - emptyBlock : undocumented empty block
  - enumSwitch : incomplete enum switch
  - fieldHiding : field hiding another variable
  - finalBound : type parameter with final bound
  - finally : finally block not completing normally
  - indirectStatic : indirect reference to static member
  - intfAnnotation : annotation type used as super interface
  - intfNonInherited : interface non-inherited method compatibility
  - javadoc : invalid javadoc
  - localHiding : local variable hiding another variable
  - maskedCatchBlock : hidden catch block
  - nls : string literal lacking non-nls tag //$NON-NLS-<n>$
  - noEffectAssign : assignment without effect
  - over-ann : missing @Override annotation
  - pkgDefaultMethod : attempt to override package-default method
  - semicolon : unnecessary semicolon, empty statement
  - serial : missing serialVersionUID
  - unqualifiedField : unqualified reference to field
  - unchecked : unchecked type operation
  - unusedArgument : unread method parameter
  - unusedImport : unused import declaration
  - unusedLocal : unread local variable
  - unusedPrivate : unused private member declaration
  - unusedThrown : unused declared thrown exception
  - unnecessaryElse : unnecessary else clause
  - uselessTypeCheck : unnecessary cast/instanceof operation
  - specialParamHiding : constructor or setter parameter hiding another field
  - staticReceiver : non-static reference to static member
  - syntheticAccess : synthetic access for innerclass
  - typeHiding : type parameter hiding another type
  - varargsCast : varargs argument need explicit cast
  - warningToken : unhandled warning token
- SearchMatch now has a implicit field which shows whether the associated element is implicit or not (see bug 94062).
  Added new API methods to access this field:
  - `SearchMatch#isImplicit()`
  - `SearchMatch#setImplicit(boolean)`

## What's new in this drop

- Code Assist doesn't propose anymore type completion when completion token is empty.
  Note: the code to propose completion when token is empty is not removed. Change the value of Completion.NO_TYPE_COMPLETION_ON_EMPTY_TOKEN to re-enabled this behavior.
- @SuppressWarnings is now supported. Recognized warning names are: `"all"`, `"deprecation"`, `"serial"`, `"unchecked"`, `"finally"`.
- Changed Code Assist options.
  CODEASSIST_FORBIDDEN_REFERENCE_CHECK and CODEASSIST_DISCOURAGED_REFERENCE_CHECK are replaced by CODEASSIST_HIDE_RESTRICTED_REFERENCES.

      /*
       *  CODEASSIST / Hide Proposals for Restricted Completions
       *    When value is "never", never hide proposals for restricted completions.
       *    When value is "error", hide proposals for restricted completions if insertion of these completions would create a compile error.
       *    When value is "warning", hide proposals for restricted completions if insertion of these completions would create a compile error or warning.
       *    To configure the severity of restrictions, "org.eclipse.jdt.core.compiler.problem.forbiddenReference"
       *    option must be used for forbidden reference and "org.eclipse.jdt.core.compiler.problem.discouragedReference"
       *    option must be used for discouraged reference.
       *     - option id:         "org.eclipse.jdt.core.codeComplete.restrictionsCheck"
       *     - possible values:   { "never", "error", "warning" }
       *     - default:           "error"
       */
       public static final String CODEASSIST_HIDE_RESTRICTED_REFERENCES;

- Removed 3.1 APIs `BindingKey#getDeclaringTypeSignature()` and `BindingKey#toSignature()` as they were found error prone. See bug 93105 for details.
- Added support for 'capture' inside Code Assist. Delaring type of a completion proposal is captured for qualified completion.
- Added APIs to replace a range of moved nodes (`ListRewrite#createMoveTarget(first, last, replacingNode, editGroup)`). See bug 91938 for details.

# Eclipse Platform Build Notes

Eclipse SDK 3.1M7 - 26th April 2005
Project org.eclipse.jdt.core v_553 (cvs).

## What's new in this drop

- Removed the need to load `java.lang.RuntimeException` and `java.lang.Error` eagerly during compilation when assessing unchecked exception diagnosis. This allows Java class library developpers to be more minimalistic.
- Fix for bug 83230 required the index version to be incremented. Indexes will be automatically regenerated upon subsequent search queries (accounting for indexing notification in search progress dialogs).
- Added support for Javadoc in package-info.java. Compiler now verifies package comment tags syntax and references for this compilation unit. See bug 83804 for further details.

Eclipse SDK 3.1M6 - 1st April 2005
Project org.eclipse.jdt.core v_548 - 3.1 MILESTONE 6 (cvs).

## What's new in this drop

- New Code Formatter built-in profile has been added: "Eclipse [built-in]".
  This new profile is based on "Java Conventions" but uses tab character (instead of space) and set tab size to 4 (instead of 8).
  JavaCore was using these values by default but they were wrongly showed as "Java Conventions" in Code Formatter preference page. This problem is now fixed (see bug 89739).
  Code formatter behavior is still fully compatible with previous milestones for users who have not modified Code Formatter options in their workspace. However, users who have explicitely modified them and have troubles with use of tab character, should open Code Formatter preference page and either select this new "Eclipse" profile or verify state of "Use of tab character" check-box.

### Problem Reports Fixed

89982 [1.5][compiler] Internal failure during missing enum case diagnosis

Eclipse SDK 3.1M6 - 22nd March 2005
Project org.eclipse.jdt.core v_542 (cvs).

## What's new in this drop

- The internal build state format has changed and a full build is expected when restarting an existing workspace with this version of JDT Core.
- Added the following APIs to control access rules severity:
  - `org.eclipse.jdt.core.IAccessRule`
    - `int K_ACCESSIBLE;`
    - `int K_NON_ACCESSIBLE;`
    - `int K_DISCOURAGED;`
    - `IPath getPattern();`
    - `int getKind();`
  - `org.eclipse.jdt.core.JavaCore`
    - `String COMPILER_PB_DISCOURAGED_REFERENCE;`
    - `IAccessRule newAccessRule(IPath pattern, int kind);`
    - `IClasspathEntry newContainerEntry( IPath containerPath, IAccessRule[] accessRules, IClasspathAttribute[] extraAttributes, boolean isExported);`
    - `IClasspathEntry newLibraryEntry( IPath path, IPath sourceAttachmentPath, IPath sourceAttachmentRootPath, IAccessRule[] accessRules, IClasspathAttribute[] extraAttributes, boolean isExported);`
    - `IClasspathEntry newProjectEntry( IPath path, IAccessRule[] accessRules, boolean combineAccessRules, IClasspathAttribute[] extraAttributes, boolean isExported);`
    - `IClasspathEntry newVariableEntry( IPath variablePath, IPath variableSourceAttachmentPath, IPath variableSourceAttachmentRootPath, IAccessRule[] accessRules, IClasspathAttribute[] extraAttributes, boolean isExported);`
  - `org.eclipse.jdt.core.IClasspathEntry`
    - `boolean combineAccessRules();`
    - `IAccessRule[] getAccessRules();`
- Code select now works into Javadoc comment wherever a reference can be specified (i.e. @see, @link, @linkplain, @throws, @exception, @param or @value tags)
  (see bug 54968).
  For example, hit F3 with cursor located in `MyClass`, in following Javadoc comment:

      /**
       * @see MyClass This is my class
       */

  will open editor on MyClass.java file.
- New CodeSelect feature: Code select return an element if the selection is an enum constant inside a switch label.

      Colors c;
      swith(c) {
        case BLUE:
        case RED; // select RED
      }

- Added new kind of type signature: `Signature#WILDCARD_TYPE_SIGNATURE`.
  `Signature#getTypeSignatureKind(char[])` and `Signature#getTypeSignatureKind(String)` now return `Signature#WILDCARD_TYPE_SIGNATURE` if the signature is a wildcard : * or +Ljava.lang.Object; or -Ljava.lang.Object;
- Added new completion API to describe context in which the completion occurs.
  Currently only the expected types of the potential completion proposals are proposed.

       X x = zzz<complete here>

  In this example the expected type is `X`. It is not mandatory to a proposal to respect this expectation and it is possible that there is no completion proposal.

      public class CompletionContext  {
        public char[][] getExpectedTypesSignatures() {...}
        public char[][] getExpectedTypesKeys() {...}
      }

  Client must override `CompletionRequestor#acceptContext(..)` to know the context. This method call ocurs after the call to `beginReporting()` and before the call to any `accept(CompletionProposal)` method.

      public class CompletionRequestor {
        ...
        public void acceptContext(CompletionContext context) {..}
        ...
      }

# Eclipse Platform Build Notes
Java development tools core

Eclipse SDK 3.1M6 - 15th March 2005
Project org.eclipse.jdt.core v_541 (cvs).

## What's new in this drop

- Compiler now recognizes `@Deprecated` annotations, and treats them equivalent to doc comment `/** @deprecated */`.
- Added optional compiler diagnosis to flag deprecated constructs missing a proper `@Deprecated` annotation (to encourage using annotations instead of doc comment tag). Corresponding problem IDs are: `IProblem.FieldMissingDeprecatedAnnotation`, `IProblem.MethodMissingDeprecatedAnnotation`, `IProblem.TypeMissingDeprecatedAnnotation`.

      * COMPILER / Reporting Missing @Deprecated Annotation
      *    When enabled, the compiler will issue an error or a warning whenever encountering a declaration
      *    carrying a @deprecated doc tag but has no corresponding @Deprecated annotation.
      *     - option id:        "org.eclipse.jdt.core.compiler.problem.missingDeprecatedAnnotation"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "ignore"

- JLS2 API have been deprecated (see bug 69657).
- Allowed javadoc reference to varargs methods (see bug 87845).
  The 1.5 spec for the Javadoc tool does not mention the possibility of a variable arity indicator in method references. However, the 1.5 Javadoc tool itself does indeed support it. Since it makes sense to have a way to explicitly refer to variable arity methods, it seems more likely that the Javadoc spec is wrong in this case.
  Following API methods were added to `MethodRefParameter`:

      /**
       * The "varargs" structural property of this node type (added in JLS3 API).
       * @since 3.1
       */
      public static final SimplePropertyDescriptor VARARGS_PROPERTY;
      /**
       * Returns whether this method reference parameter is for
       * the last parameter of a variable arity method (added in JLS3 API).
       *
       * Note that the binding for the type Fooin the vararg method
       * reference #fun(Foo...) is always for the type as
       * written; i.e., the type binding for Foo. However, if you
       * navigate from the MethodRef to its method binding to the
       * type binding for its last parameter, the type binding for the vararg
       * parameter is always an array type (i.e., Foo[]) reflecting
       * the way vararg methods get compiled.
       *
       *
       * @return true if this is a variable arity parameter,
       *    and false otherwise
       * @exception UnsupportedOperationException if this operation is used in
       * a JLS2 AST
       * @since 3.1
       */
      public boolean isVarargs();
      /**
       * Sets whether this method reference parameter is for the last parameter of
       * a variable arity method (added in JLS3 API).
       *
       * @param variableArity true if this is a variable arity
       *    parameter, and false otherwise
       * @since 3.1
       */
      public void setVarargs(boolean variableArity);

- Added new flags on nature of match to specify that declaring or return type should be ignored during the search (see bug 80264).
  These flags are defined on `IJavaSearchConstants` interface:

      /**
       * Ignore declaring type while searching result.
       * Can be used in conjunction with any of the nature of match.
       * @since 3.1
       */
      int IGNORE_DECLARING_TYPE = 0x10;
      /**
       * Ignore return type while searching result.
       * Can be used in conjunction with any of the nature of match.
       * Note that:
       * 	- for fields search, pattern will ignore field type
       * 	- this flag will have no effect for types search
       * @since 3.1
       */
      int IGNORE_RETURN_TYPE = 0x20;

  Note that these flags are active only for search of declarations (i.e. `IJavaSearchConstants.DECLARATIONS` and `IJavaSearchConstants.ALL_OCCURRENCES`) and while searching for IJavaElement (see doc of `SearchPattern.createPattern(IJavaElement, int)` API method).
- Improved API for type name requestor. Abstract class `TypeNameRequestor` replaces interface `ITypeNameRequestor` which is deprecated.
  There's now only a single method for type name requestor while accepting a type:

      /**
       * Accepts a top-level or a member type.
       *
       * The default implementation of this method does nothing.
       * Subclasses should override.
       *
       * @param modifiers the modifier flags of the type. Note that for source type,
       *	these flags may slightly differ from thoses get after resolution.
       *	For example an interface defined by interface A {}, although obviously public,
       *	will be returned false by Flags.isPublic(modifiers) due to the fact
       *	that its declaration does not explicitely define public flag.
       *	@see org.eclipse.jdt.core.Flags
       * @param packageName the dot-separated name of the package of the type
       * @param simpleTypeName the simple name of the type
       * @param enclosingTypeNames if the type is a member type,
       *	the simple names of the enclosing types from the outer-most to the
       *	direct parent of the type (for example, if the class is x.y.A$B$C then
       *	the enclosing types are [A, B]. This is an empty array if the type
       *	is a top-level type.
       * @param path the full path to the resource containing the type. If the resource is a .class file
       *	or a .java file, this is the full path in the workspace to this resource. If the
       *	resource is an archive (that is, a .zip or .jar file), the path is composed of 2 paths separated
       *	by IJavaSearchScope.JAR_FILE_ENTRY_SEPARATOR:
       *	the first path is the full OS path to the archive (if it is an external archive),
       *	or the workspace relative IPath to the archive (if it is an internal archive),
       *	the second path is the path to the resource inside the archive.
       */
      public void acceptType(int modifiers, char[] packageName, char[] simpleTypeName, char[][] enclosingTypeNames, String path)

  Clients can now distinguish Annotation, Enum, Interface and Class using `Flags` API methods on `modifiers` parameter.
- Added support for package-info.java. This allows to define annotations on the package declaration. See bug 86167 for further details.
- Added API `JavaCore#newProjectEntry(IPath, IPath[], IPath[], boolean, IClasspathAttribute[], boolean)` that take a 'combineAccessRestrictions' flag to control whether access restrictions of exported libraries of the project should be combined with the access restrictions of this project entry.
- Added API method `AST#newName(String qualifiedName)` for creating `SimpleName` or `QualifiedName` nodes depending on the form of the given name string.

## What's new in this drop

- Fix for bug 83319 required the index version to be incremented. Indexes will be automatically regenerated upon subsequent search queries (accounting for indexing notification in search progress dialogs).
- Added optional compiler diagnosis to flag incomplete enum switch statements. Corresponding problem ID is: `IProblem.MissingEnumConstantCase`

      * COMPILER / Reporting Incomplete Enum Switch
      *    When enabled, the compiler will issue an error or a warning whenever an enum constant has
      *    no corresponding case label in an enum switch statement
      *    type has no case label matching an enum constant.
      *     - option id:        "org.eclipse.jdt.core.compiler.problem.incompleteEnumSwitch"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "ignore"

- Added API `org.eclipse.jdt.core.dom.CompilationUnit#getJavaElement()` to retrieve the compilation unit or class file the compilation unit node was created from.
- Added API `IMethodBinding#isSubsignature(IMethodBinding)` to find out if a method's signature is a subsignature of another method.
- Added optional compiler diagnosis to flag method overriding a superclass method, but missing proper `@Override` annotation. Corresponding problem ID is: `IProblem.MissingOverrideAnnotation`

      * COMPILER / Reporting Missing @Override Annotation
      *    When enabled, the compiler will issue an error or a warning whenever encountering a method
      *    declaration which overrides a superclass method but has no @Override annotation.
      *     - option id:        "org.eclipse.jdt.core.compiler.problem.missingOverrideAnnotation"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "ignore"

- New CodeAssist feature: Enum constant are proposed inside switch label if the expression is an enum.

      Colors c;
      swith(c) {
        case BLUE:
        case RED<complete here>
      }

- New CodeAssist feature: Annotation's attribute name are proposed.

      @Annot(attr<complete here>=value)

  To propose this new completion kind a new API has been added: CompletionProposal.ANNOTATION_ATTRIBUTE_REF.

      /**
       * Completion is a reference to annotation's attribute.
       * This kind of completion might occur in a context like
       * <code>"@Annot(attr^=value)"</code> and complete it to

Eclipse SDK 3.1M6 - 22nd February 2005
Project org.eclipse.jdt.core v_538 (cvs).

## What's new in this drop

- Inclusion/exclusion filters used as import restrictions have been renamed into 'accessible files' and 'non accessible files' patterns. The following APIs have been added on `IClasspathEntry`: `getAccessibleFiles()` and `getNonAccessibleFiles()`. These are valid only for library, project, container and variable entries. `getInclusionPatterns()` and `getExclusionPatterns()` temporary return the accessible files and non accessible files patterns for these entries.
- Added ability to associate classpath attributes to a classpath entry (see `IClasspathAttribute`). A classpath attribute is created using `JavaCore#newClasspathAttribute(String, String)`. Then one can associate this attribute with a classpath entry using one of:
  - `JavaCore#newContainerEntry(IPath containerPath, IPath[] accessibleFiles, IPath[] nonAccessibleFiles, IClasspathAttribute[] extraAttributes, boolean isExported)`
  - `JavaCore#newLibraryEntry(IPath path, IPath sourceAttachmentPath, IPath sourceAttachmentRootPath, IPath[] accessibleFiles, IPath[] nonAccessibleFiles, IClasspathAttribute[] extraAttributes, boolean isExported)`
  - `JavaCore#newProjectEntry(IPath path, IPath[] accessibleFiles, IPath[] nonAccessibleFiles, IClasspathAttribute[] extraAttributes, boolean isExported)`
  - `JavaCore#newSourceEntry(IPath path, IPath[] inclusionPatterns, IPath[] exclusionPatterns, IPath specificOutputLocation, IClasspathAttribute[] extraAttributes)`
  - `JavaCore#newVariableEntry(IPath variablePath, IPath variableSourceAttachmentPath, IPath variableSourceAttachmentRootPath, IPath[] accessibleFiles, IPath[] nonAccessibleFiles, IClasspathAttribute[] extraAttributes, boolean isExported)`
- Added optional compiler diagnosis when a type parameter declaration is hiding another type. Corresponding problem ID is: `IProblem.TypeParameterHidingType`

      * COMPILER / Reporting Type Parameter Declaration Hiding another Type
      *    When enabled, the compiler will issue an error or a warning whenever a type parameter
      *    declaration is hiding some type.
      *     - option id:         "org.eclipse.jdt.core.compiler.problem.typeParameterHiding"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "warning"

- The predicates `isInterface()` on Java element and DOM AST are now answering `true` for annotation types. Indeed, annotation types are allowed to be implemented just like regular interfaces.
- Added optional compiler diagnosis signalling usage of an annotation type as a super interface. Corresponding problem ID is: `IProblem.AnnotationTypeUsedAsSuperInterface`

      * COMPILER / Reporting Use of Annotation Type as Super Interface
      *    When enabled, the compiler will issue an error or a warning whenever an annotation type is used
      *    as a super-interface. Though legal, this is discouraged.
      *     - option id:         "org.eclipse.jdt.core.compiler.problem.annotationSuperInterface"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "warning"

## What's new in this drop

- Tuned generic method type argument inference (JLS 15.12.2.7&8).
- Optional diagnosis for assignment with no effect now also detects: "var = var++;" scenario.
- Added APIs `IType#getKey()`, `IField#getKey()`, `IMethod#getKey()` that return a binding key for these Java elements.
- Added APIs `IType#isResolved()`, `IField#isResolved()`, `IMethod#isResolved()` that return whether these Java elements are resolved elements and thus whether their key (see above) contains resolved information.
- Added API class `org.eclipse.jdt.core.BindingKey` to decode a binding key obtained from `IBinding#getKey()` or one of the `getKey()` methods above.

## What's new in this drop

- Search engine is now able to find references and declarations to ITypeParameter.
  To perform this kind of search, clients need to create a pattern using `SearchPattern.createPattern(IJavaElement,int,int)` providing searched ITypeParameter for IJavaElement parameter.
- `TypeParameter#resolveBinding()` now returns an `ITypeBinding` instead of an `IBinding`
- Java model operations have been ported off the deprecated JDOM. They now use AST rewrite. This enables these operations on local and anonymous types, enumerations and annotation types.

## What's new in this drop

- Support for generic methods/constructors search has been added to SearchEngine (see bug 75642).
  User can now search for declaration and/or references to generic methods/constructors or parameterized methods/constructors (like `public <U> void foo(U u){}` or `<String>foo("")` for example). This search can be done either selecting a JavaElement or using Java Search dialog.
- Added new API `JavaConventions#validateTypeVariableName(String)`.
- Added new API `JavaCore#newTypeHierarchy(IRegion,WorkingCopyOwner,IProgressMonitor)` that creates a hierarchy independently of a project.

## What's new in this drop

- Added API `ASTParser#createBindings(IJavaElement[],IProgressMonitor)` to create the DOM bindings for the given Java elements.
- Fix for bug 82004 required the index version to be incremented. Indexes will be automatically regenerated upon subsequent search queries (accounting for indexing notification in search progress dialogs).
- Merged problem `IProblem.UnnecessaryArgumentCast` with `IProblem.UnnecessaryCast` since it provided little additional value, and was rather perceived as confusing. From now on, only `IProblem.UnnecessaryCast` is reported.

## What's new in this drop

- Added optional compiler diagnosis reporting when boxing/unboxing conversion is performed. Corresponding problem IDs are: `IProblem.BoxingConversion` and `IProblem.UnboxingConversion`.

      * COMPILER / Reporting Boxing/Unboxing Conversion
      *    When enabled, the compiler will issue an error or a warning whenever a boxing or an unboxing
      *    conversion is performed.
      *     - option id:         "org.eclipse.jdt.core.compiler.problem.autoboxing"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "ignore"

- Renamed unsafe type operation optional problem into unchecked type operation, to better match notion of "unchecked" warning from JLS 3rd edition.

      * COMPILER / Reporting Unchecked Type Operation
      *    When enabled, the compiler will issue an error or a warning whenever an operation involves generic types, and potentially
      *    invalidates type safety since involving raw types (e.g. invoking #foo(X<String>) with arguments  (X)).
      *     - option id:         "org.eclipse.jdt.core.compiler.problem.uncheckedTypeOperation"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "warning"

## What's new in this drop

- Initial support for search on annotations has been implemented. Declarations or references to annotation types are now found by search engine.
  However, it is not currently able to find annotation member (fields or methods). This should be done for next milestone.
- SearchPattern now accept two new flags for match rule: R_ERASURE_MATCH and R_EQUIVALENT_MATCH (see bug 79790).

      	/**
      	 * Match rule: The search pattern matches search results as raw types or parameterized types with same erasure.
      	 * Example:
      	 *	- pattern: List<Exception>
      	 *	- match: List<Object>
      	 * Can be combined to all other match rules, e.g. {@link #R_CASE_SENSITIVE} | {@link #R_ERASURE_MATCH}
      	 * This rule is not activated by default, so raw types or parameterized types with same erasure will not be found
      	 * for pattern List<String>,
      	 * Note that with this pattern, the match selection will be only on the erasure even for parameterized types.
      	 * @since 3.1
      	 */
      	public static final int R_ERASURE_MATCH = 16;
      	/**
      	 * Match rule: The search pattern matches search results as raw types or parameterized types with equivalent type parameters.
      	 * Example:
      	 *	- pattern: List<Exception>
      	 *	- match:
      	 * 		+ List<? extends Throwable>
      	 * 		+ List<? super RuntimeException>
      	 * 		+ List<?>
      	 * Can be combined to all other match rules, e.g. {@link #R_CASE_SENSITIVE} | {@link #R_EQUIVALENT_MATCH}
      	 * This rule is not activated by default, so raw types or equivalent parameterized types will not be found
      	 * for pattern List<String>,
      	 * This mode is overridden by {@link  #R_ERASURE_MATCH} as erasure matches obviously include equivalent ones.
      	 * That means that pattern with rule set to {@link #R_EQUIVALENT_MATCH} | {@link  #R_ERASURE_MATCH}
      	 * will return same results than rule only set with {@link  #R_ERASURE_MATCH}.
      	 * @since 3.1
      	 */
      	public static final int R_EQUIVALENT_MATCH = 32;

  Added new API method to make this flag settable even while creating pattern using a IJavaElement:
  - `SearchPattern#createPattern(IJavaElement element, int limitTo, int matchRule)`
- SearchMatch now has a rule field which shows the rule used while reporting the match (initial implementation for bug 79866).
  Added new API methods to access this field:
  - `SearchMatch#getRule()`
  - `SearchMatch#setRule(int)`
- Added API IType#getFullyQualifiedParameterizedName() that shows the type parameter/arguments if the type is generic/parameterized.
- Added support in Java model for annotation types and annotations.
- Support for indexing annotation types required the index version to be incremented. Indexes will be automatically regenerated upon subsequent search queries (accounting for indexing notification in search progress dialogs).
- Added compiler support for autoboxing
- Code Assist now works for annotations. When performing a completion inside an annotation name, proposals are possibles types and annotations types are more relevant than other types
- Code Select now works for annotations and annotation methods in correct code.
- Recovery now works for annotation type declaration and annotation method declaration

- Support for generic types search has been added to SearchEngine (see bug 75641).
  User can now search for declaration and/or references to generic types or parameterized types (like `public class List<T> {}` or `List<String>` for example). This search can of course be done either selecting a JavaElement (see following point) or using Java Search dialog.
- Support for generic types and generic methods selection has been added inside CodeSelect. When the result is a parameterized type reference, the returned JavaElement is a `ParameterizedSourceType` or `ParameterizedBinaryType`. When the result is a parameterized method invocation, the returned JavaElement is a `ParameterizedSourceMethod` or `ParameterizedBinaryMethod`. When the result is a field access to a generic type's field, the returned JavaElement is a `ParameterizedSourceField` or `ParameterizedBinaryField`.
- The internal Java model cache now adapts to the number of elements in the workspace. For example if a project has 1000 package fragment roots, the space limit of the cache of roots will increase to 1000. This size is reset to its default when the project is closed.
- Added the following compatibility rules APIs:
  - `ITypeBinding#isAssignmentCompatible(ITypeBinding)`
  - `ITypeBinding#isCastCompatible(ITypeBinding)`
  - `ITypeBinding#isSubTypeCompatible(ITypeBinding)`
  - `IMethodBinding#overrides(IMethodBinding)`

## What's new in this drop

- Support for search on enum has been implemented. Declarations or references to enum type, fields, constructors and methods are correctly found by search engine.
- Support to compute type hierarchies on enum required the index version to be incremented. Indexes will be automatically regenerated upon subsequent search queries (accounting for indexing notification in search progress dialogs).
- Added support inside CompletionEngine to not propose completion when an access restriction is violated. Currently access restrictions are applied only to top level types.
- Added code assist option to not propose completion when an access restriction is violated.

- Added first-cut of enumeration support into compiler. Requires some more work to properly diagnose error situations, and be leveraged in various JDT/Core functionalities.
- Improved problem descriptions to show ellipsis in varargs method signatures
- Added `org.eclipse.jdt.core.util.ClassFileBytesDisassembler#SYSTEM` field to support an extra-detailed output from the disassembler. It can show constant pool contents.
- In order to fix bug 76440, two APIs on `org.eclipse.jdt.core.Signature` have been added to handle var args in the signature decoding.
  - `Signature#toCharArray(char[],char[],char[][],boolean,boolean,boolean)`
  - `Signature#toString(String,String,String[],boolean,boolean,boolean)`
- Added compiler option to diagnose need for cast of varargs argument. Matching problem IDs are `IProblem.MethodVarargsArgumentNeedCast` & `IProblem.ConstructorVarargsArgumentNeedCast`

Project org.eclipse.jdt.core v_515 (cvs).

## What's new in this drop

- Code assist use static imports to propose completions.
- 2 new Javadoc compiler options have been added (see bugs 53977 and 75701).
  While reporting problems on invalid Javadoc tags, user can now decide not to report deprecation and/or visibility warnings on references used in @see, @link or @values tags.
  Here's the description of these new options:

      	 * COMPILER / Reporting Invalid Javadoc Tags with Deprecated References
      	 *    Specify whether the compiler will report deprecated references used in Javadoc tags.
      	 *    Note that this diagnosis can be enabled based on the visibility of the construct associated with the Javadoc;
      	 *    also see the setting "org.eclipse.jdt.core.compiler.problem.invalidJavadocTagsVisibility".
      	 *     - option id:         "org.eclipse.jdt.core.compiler.problem.invalidJavadocTagsDeprecatedRef"
      	 *     - possible values:   { "enabled", "disabled" }
      	 *     - default:           "enabled"
      	 *
      	 * COMPILER / Reporting Invalid Javadoc Tags with Not Visible References
      	 *    Specify whether the compiler will report non-visible references used in Javadoc tags.
      	 *    Note that this diagnosis can be enabled based on the visibility of the construct associated with the Javadoc;
      	 *    also see the setting "org.eclipse.jdt.core.compiler.problem.invalidJavadocTagsVisibility".
      	 *     - option id:         "org.eclipse.jdt.core.compiler.problem.invalidJavadocTagsNotVisibleRef"
      	 *     - possible values:   { "enabled", "disabled" }
      	 *     - default:           "enabled"
      	 *

- Changed build state format to record access restrictions. As a consequence, a full rebuild will be required when reusing existing workspaces.
- Added tracing (org.eclipse.jdt.core/debug/resolution) to show the number of packages, roots and working copies used during name resolution.
- New API `org.eclipse.jdt.core.dom.EnumDeclaration#enumConstants()`. The enum constants are now in a separate list from the body declarations. The `org.eclipse.jdt.core.dom.EnumDeclaration#getEnumConstants()` method has been deprecated and will be removed after M3. See bug 76190 for further details.
- New requestor API `CompletionRequestor` is implemented inside code assist engine.
- Added missing API to `IType` for new completion requestor support:
  - `IType#codeComplete(char[],int,int,char[][],char[][],int[],boolean,CompletionRequestor,WorkingCopyOwner)`
  - `IType#codeComplete(char[],int,int,char[][],char[][],int[],boolean,CompletionRequestor)`
- Added missing API to `IEvaluationContext` for new completion requestor support:
  - `IEvaluationContext#codeComplete(String,int,CompletionRequestor, WorkingCopyOwner)`
  - `IEvaluationContext#codeComplete(String,int,CompletionRequestor)`
- Added new API inside `Signature` to extract package name part or type name part of a type signature:
  - `Signature#getSignatureQualifier(char[])`
  - `Signature#getSignatureQualifier(String)`
  - `Signature#getSignatureSimpleName(char[])`
  - `Signature#getSignatureSimpleName(String)`
- Added support in Java model for varargs methods:
  - `Flags.isVarargs(method.getFlags())` now returns whether the method is a varargs method.
  - Operations that resolve (like reconcile, search, etc.) now convert varargs source methods into varargs MethodDeclarations.
- Introduced access restrictions so as to better enforce API contracts across components.

  Problem: Libraries are usually packaged to contain both API for compile-time and implementation for runtime; and thus expose a superset of the API contract to client programs, allowing them to make forbidden assumptions on internals (a typical restriction for Eclipse developpers is to not use internal classes from prerequisite plug-ins). One solution for solving this issue is to separate the API from its implementation into 2 distinct libraries (compile-time/runtime) and then use the classpath rules to only include the API portion on the classpath for compiling. However, this usually proves to be unrealistic, since the API is often mixed with some implementation aspects (not officially part of the API) which are carrying references to its internals (supertype hierarchy, field or method signatures). When it happens, then the compiler needs the implementation also to be on the classpath in order to resolve all signatures appropriately; which goes back to the original problem of exposing too much to unaware clients.

  Instead, we allowed classpath rules to be associated with some import restrictions so as to select portions of prerequisite projects or libraries which are legal to use inside this project. Access restrictions are expressed as inclusion/exclusion rules on classpath entries (using Ant fileset notation for discriminating on package and/or file names, e.g. `excluding='**/internal/'` would exclude all types defined any `internal` package), and can be associated to project, library, classpath variable or classpath container classpath entries. Note that restrictions are automatically combined along a classpath chain. For instance, if a classpath container entry is associated with some restrictions, then when resolved to a set of entries, these will automatically inherit the container restrictions (and could still provide further custom restrictions on a per entry basis).

  When a forbidden reference to a restricted type is detected, the compiler will issue a problem which severity can be controlled by JavaCore preference "org.eclipse.jdt.core.compiler.problem.forbiddenReference". Corresponding problem marker ID is `IProblem.ForbiddenReference`.

      * COMPILER / Reporting Forbidden Reference to Type with Restricted Access
      *    When enabled, the compiler will issue an error or a warning when referring to a type with restricted access, as defined according
      *    to the access restriction specifications.
      *     - option id:         "org.eclipse.jdt.core.compiler.problem.forbiddenReference"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "ignore"

  In order to challenge this new functionality before leveraged in UI or PDE, Eclipse developpers need to perform the following two actions:

  1. edit some .classpath file to exclude all types located in "**/internal/" packages from prerequisites; i.e. replace line

         	<classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins"/>

     with

         	<classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins" excluding="**/internal/"/>

  2. enable compiler warning for forbidden references, i.e. add the following line to the workspace default preferences located in: `<workspace>\.metadata\.plugins\org.eclipse.core.runtime\.settings\org.eclipse.jdt.core.prefs`

         	org.eclipse.jdt.core.compiler.problem.forbiddenReference=warning

     Note: alternatively, it could be specified on a per project basis, by adding line to `<project>/.settings/org.eclipse.jdt.core.prefs`.
- Static imports are now supported:

      import static type.*;
      import static type.identifier;

  Java Search is also able to find referenced type, field and/or member in static imports but required the index version to be incremented.
  Indexes will be automatically regenerated upon subsequent search queries (accounting for indexing notification in search progress dialogs).

## What's new in this drop

- Type search works with generic (only for string pattern, see bug 75641).
  For example, user can enter `List<String>` in Java Search text and search for type references.
  Match(es) will be found if this parameterized type is used in the search scope.
  Note that some API changes still need to be done to make generic type search work while selecting a parameterized type from Java editor.
- Field search works with generic (see bug 73277).
  For example, user can search for references to a field declared as

      List<String> ls;

  Match(es) will be found if this field is used in the search scope.

## What's new in this drop

- The batch compiler now support 5 as a valid version number for -target and -source options. 5 is equivalent to 1.5.
- Added support for static imports. Can now import all static members of a type, such as `java.lang.Math`.
- Added new API `IBinding#getJavaElement()` to get the Java element corresponding to a `org.eclipse.jdt.core.dom.IBinding`.

Eclipse SDK 3.1M1 - 27th July 2004 - Codename "Cheetah"
Project org.eclipse.jdt.core v_501 (cvs).

## What's new in this drop

- Plugin version ID got incremented to 3.1.0.
- Added support for method return type covariance
- Added optional compiler diagnosis for serializabe classes missing a declaration of serialVersionUID field. Corresponding problem ID is IProblem.MissingSerialVersion.

    * COMPILER / Reporting Missing Declaration of serialVersionUID Field on Serializable Class
    *    When enabled, the compiler will issue an error or a warning whenever a serializable class is missing a local declaration
    *    of a serialVersionUID field. This field must be declared as static final and be of type long.
    *     - option id:         "org.eclipse.jdt.core.compiler.problem.missingSerialVersion"
    *     - possible values:   { "error", "warning", "ignore" }
    *     - default:           "warning"

- Added `isConstructor()` and `isSynthetic()` getters to MethodReferenceMatch.
  When a search requestor (`SearchRequestor`) accepts this kind of match, it can now distinguish between method and constructor reference matches. It can also know if a constructor reference match is a default constructor or use an implicit super call.
  Note that synthetic method reference match is not supported yet.
- Once 1.5 source compliance is enabled, the typecheck rules for conditional operator (a ? b : c) allows scenario where 'b' and 'c' have a common supertype (i.e. it is no longer required for one to be assignable to the other as in the past). This is required by JLS 3rd edition.
- Fix for bug 69028 requires the index version to be incremented. Indexes will be automatically regenerated upon subsequent search queries (accounting for indexing notification in search progress dialogs).
- The spec for MethodDeclaration.typeParameters was changed to remove the clause that said that type parameters were not meaningful for constructors. According to the latest JLS3, both constructors and methods are allowed to have type parameters. (bug 70665).

## What's new in this drop

- From target 1.5 on, the JSR bytecode instruction is no longer generated. As a consequence, the corresponding compiler option status will be ignored as soon as -target 1.5 is specified.
- Batch compiler defaults to 1.5 source and target, when toggled in 1.5 compliant mode ("-1.5").
- Added support for generics to JavaModel, thus enabling editor problem reconciling, outliner, type hierarchies.
- Improved codeassist and codeselect handling of generics

- JDK 1.5 support.
- JavaCore 1.5 specific options. Either augmented to consider 1.5 or added.

      * COMPILER / Setting Compliance Level
      *    Select the compliance level for the compiler. In "1.3" mode, source and target settings
      *    should not go beyond "1.3" level.
      *     - option id:         "org.eclipse.jdt.core.compiler.compliance"

      *     - default:           "1.4"
      *
      * COMPILER / Setting Source Compatibility Mode
      *    Specify whether which source level compatibility is used. From 1.4 on, 'assert' is a keyword
      *    reserved for assertion support. Also note, than when toggling to 1.4 mode, the target VM
      *   level should be set to "1.4" and the compliance mode should be "1.4".
      *   Source level 1.5 is necessary to enable generics, autoboxing, covariance, annotations, enumerations
      *   enhanced for loop, static imports and varargs. Once toggled, the target VM level should be set to "1.5"
      *   and the compliance mode should be "1.5".

      *     - default:           "1.3"
      *
      * COMPILER / Defining Target Java Platform
      *    For binary compatibility reason, .class files can be tagged to with certain VM versions and later.
      *    Note that "1.4" target require to toggle compliance mode to "1.4" too. Similarily, "1.5" target require
      *    to toggle compliance mode to "1.5".

      *     - possible values:   { "1.1", "1.2", "1.3", "1.4", "1.5" }

      * COMPILER / Reporting Unsafe Type Operation
      *    When enabled, the compiler will issue an error or a warning whenever an operation involves generic types, and potentially
      *    invalidates type safety since involving raw types (e.g. invoking #foo(X<String>) with arguments  (X)).
      *     - option id:         "org.eclipse.jdt.core.compiler.problem.unsafeTypeOperation"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "warning"
      *
      * COMPILER / Reporting final Bound for Type Parameter
      *    When enabled, the compiler will issue an error or a warning whenever a generic type parameter is associated with a
      *    bound corresponding to a final type; since final types cannot be further extended, the parameter is pretty useless.
      *     - option id:         "org.eclipse.jdt.core.compiler.problem.finalParameterBound"
      *     - possible values:   { "error", "warning", "ignore" }
      *     - default:           "ignore"
