There are several NPEs before the deadlock.
Test caused this deadlock is
org.netbeans.test.java.sourceexception.ClassChanged.ClassChanged

NPE:
 java.lang.NullPointerException
[ideTestRunner] 	at
org.netbeans.modules.java.codesync.ModelEventAdapter.checkType(ModelEventAdapter.java:449)

It looks like a bridge issue. Dane, can you take a look at it?
Comment 3 Daniel Prusa 2004-07-22 16:50:49 UTC 
I have fixed the NPE, but I am not sure if it was the cause of the
deadlock - I was not able to reproduce the deadlock with the fix,
neighter without it.
