Description Martin Entlicher 2009-07-24 16:38:11 UTC 
During fast stepping while having turned on monitors in Debugging view, occasionally IncompatibleThreadStateException:
Unexpected JDWP Error: 13 is thrown:

INFO [org.netbeans.modules.debugger.jpda.models.JPDAThreadImpl]: Thread 'solver 0': status = 1, is suspended = true,
suspend count = 1, is at breakpoint = false, internal suspend status = false

Comment 1 Martin Entlicher 2009-07-24 16:41:46 UTC 
This might be a recent regression, the thread is suspended just to process an event and should look like running to the
outside world. The thread can be teporarily resumed to invoke a method. It looks like such resume cause this error.

Not really reproducible, occurs occasionally during fast steps.
Comment 2 Martin Entlicher 2009-08-10 15:19:48 UTC 
I'm currently not able to reproduce. Downgrading to P4 until we get more information and feedback.
Comment 3 Martin Entlicher 2009-12-02 13:01:57 UTC 
IMHO this is fixed now.
