Provides the support for the current debugging context (thread and stack frame) utilized by many of the graphical views.

The current context of the debugging session is maintained by an implementation of DebuggingContext. The context is set and cleared by an instance of Session according to events received from the debuggee.

The DebuggingContext implementations are accessed via the ContextProvider static class. To provide custom implementations of DebuggingContext, you must install your implementation as a "service". See the NetBeans OpenAPIs documentation under "Services & Lookup" to learn how this is done.
