Description tboerkel 2003-01-29 08:24:52 UTC 
Did a GetLatestVersion. When it was finished, did a 
compile all. After that was finished, scrolled in the 
editor. Then NB froze.
- JDK 1.4.1_01
- NB Q-Build NetBeansIDE-QBE200301150100-200301192142.zip
- VSS 6.0c
Attaching ThreadDump.

ThreadDump.
Comment 2 Martin Entlicher 2003-01-29 08:30:38 UTC 
Hmm, it does not look it's really frozen. Isn't it a rather
performance problem? Isn't garbage collector running?
There is no deadlock in the thread dump you've attached.
Comment 3 tboerkel 2003-01-29 08:55:56 UTC 
Waited for 2 minutes (on a 1.6 GHz machine), then made the 
ThreadDump and then killed NB.
Comment 4 tboerkel 2003-01-29 09:04:38 UTC 
BTW, using -J-XX:+UseConcMarkSweepGC, so there should be 
no hangs at all from the GC.
Comment 5 Martin Entlicher 2003-01-29 09:39:32 UTC 
Well, I have bad experience with UseConcMarkSweepGC. It works O.K. for
some time, but if you have NetBeans running for the whole day and use
them extensively, after some time it becomes very slow. It looks like
it's frozen, but it's not. When I did exit, it took 20-30 minutes! I
believe, that this is not a problem of NetBeans, because I've never
had this problem without UseConcMarkSweepGC.

This issue looks like the same problem. NetBeans are not frozen, so
from the thread dump it's not apparent where the problem is.

I'm resolving this as invalid, because it either is not a problem of
NetBeans but JVM, or it is some kind of performance problem, that can
not be detected from the attached thread dump.
Comment 6 tboerkel 2003-01-29 10:29:38 UTC 
Actually, NB was running over night, so maybe this is a 
problem with the JDK, maybe this one?

Comment 7 Martin Entlicher 2003-01-29 11:38:05 UTC 
Yes, it looks like the described problem.
It's actually a duplicate of
http://developer.java.sun.com/developer/bugParade/bugs/4758307.html
which suggests not to use the concurrent collector at all. The bug is
in progess so hopefully they will fix it soon.
Comment 8 tboerkel 2003-01-29 12:07:08 UTC 
Problem is, without the Concurrent GC, NB is much less 
responsive.
Comment 9 Jiri Kovalsky 2003-01-29 12:33:41 UTC 
Okay, then verifying as invalid bug.
