Description tboerkel 2003-01-23 08:13:08 UTC 
While this happened in the Auto Comment tool, I somehow 
don't think it is its fault. See also issue #30299.
Using NB 3.4.1 with JDK 1.4.1_01.
Attaching ThreadDump.

That seems like problem in JVM Thread is waiting on monitor entry for

Can you reproduce it?

It's not exactly reproducable. It just hangs after working 
much in a relatively short time. We have at least one 
additional machine where it also happens. I am waiting for 
a thread dump from that one.
Is it possible that this is a Java2D problem?
Comment 5 pzajac 2003-01-29 15:55:35 UTC 
P Nejedly, please evaluate this bug.
Comment 6 Petr Nejedly 2003-01-31 13:09:19 UTC 
Both this and issue #30299 seem to me like some problem in JVM. In
both dumps, several threads are
waiting for new char[] or some other allocation
to happen. Like if the JVM internal heap allocator
mutex went crazy...

Maybe this is related to issue #30464?
Comment 8 pzajac 2003-01-31 14:38:06 UTC
