Bug #213838 - Not working "Close" button when debugging session is paused & continued

http://netbeans.org/bugzilla/show_bug.cgi?id=213838

Description:
Application gets frozen sometimes after Pause & Continue. The problem 
is, that VirtualMachine.resume() was not called, only a set of threads 
was resumed. Due to this, some new threads did not start up.

Fix:
There can be some internal debugger threads, whose name matches pattern 
ThreadsCache.THREAD_NAME_FILTER_PATTERN, and they were not taken into 
account by Continue. Due to them, VirtualMachine.resume() was not 
called, because these internal threads are not suspended by Pause action.

Risk:
We're not aware of any.

Changeset:
