The cause is likely the same as in issue #156408.

*** This issue has been marked as a duplicate of 156408 ***
Comment 3 limo42 2009-06-15 13:52:03 UTC
Either not fixed or mapping to here is incorrect, because there are two new duplicates of Exception Report #145300 in
Comment 4 Martin Entlicher 2009-06-15 14:34:15 UTC
Yes, since this still occurs, it does not seem to be fully fixed by issue #156408.
I wonder why exception reporter did not open it by itself.

Similar problem can be encountered when a breakpoint is hit (see
Comment 7 Martin Entlicher 2009-07-02 15:18:54 UTC
A possible way how this can happen is:
1) A step is about to be finished or a breakpoint is about to be hit in a thread T.
2) User invokes Continue action
3) We notify thread T that it's about to be resumed (the thread is running anyway)
4) step finishes or breakpoint is hit and we start to explore stack frames
5) We call VirtualMachine.resume() which unexpectedly resumes the thread.

It looks like similar mechanism may cause method invocations to be unexpectedly paused by Pause action when it's invoked
while some method invocation is being performed.

Fixed in changeset:   137391:b8f16f4a60fa
Comment 9 Quality Engineering 2009-07-08 05:35:08 UTC
Integrated into 'main-golden', will be available in build *200907080200* on (upload may still be in progress)
Log: #158750 - Do not use VirtualMachine.resume() when there are running threads. If the threads hit an event, they get immediately resumed by this call and get out of control.
Comment 10 Quality Engineering 2010-04-29 09:48:05 UTC
Verified ... and Closing all issues resolved into NetBeans 6.7 and earlier.
