Description shemnon 2006-02-08 16:21:51 UTC 
At inexplicable times for inexpicable reasons my netbeans 5.0 will freeze the
GUI.  So this time I started it up so JConsole could attack to it, and
discovered that 10 threads including the EDT were blocked on the ExclusiveMutex
in javacore.  

I also could not figure out which thread held the lock the JMX messages returned
a -1 on teh lock owner in all 10 threads.  It could be the case of all 10
waiting on an object that will never get notified, some thread left the core
witout calling notify on the lock object.

This happens about once a week for me.  Attaching a copy of all the stack thread
traces in JConsole.

Javacore module was replaced by Retouche infrastructure. This bug is not valid
in trunk any more.
