It's likely that the thread was just started when the method was invoked - there
is IncompatibleThreadStateException thrown.
There needs to be either some synchronization or this situation must be better
handled.

Comment 4 Martin Entlicher 2008-02-14 17:24:24 UTC 
There were some fixes applied to the sychronization of method invocations and thread suspend/resume actions. Thus this
should be already fixed in NB 6.0.
Comment 5 Quality Engineering 2010-04-29 09:27:49 UTC 
Verified ... and Closing all issues resolved into NetBeans 6.7 and earlier.
