Description Oleg Khokhlov 2009-09-04 15:57:48 UTC 
Tried to create big java project (OpenJDK) as project with existing sources and NB was completely frozen after some time
(during scanning). No OOMEs.

Product Version: NetBeans IDE Dev (Build 200909030951)
Java: 1.6.0_13; Java HotSpot(TM) Client VM 11.3-b02
System: Windows XP version 5.1 running on x86; Cp1252; en_US (nb)

Comment 2 Vitezslav Stejskal 2009-09-07 10:20:31 UTC 
I'm sorry, but the dump shows nothing. No activity, no deadlock, it doesn't even contain the 'Parsing & Indexing Loop'
thread. If this is reproducible please try again and use Profile Me! and attach the profiler snapshot here. It may also
be useful to run the IDE with -J-Dorg.netbeans.modules.parsing.impl.indexing.RepositoryUpdater.level=FINE and attach it
here. Thanks

I just attached a stack dump to bug#165137 where the IDE just locked up and needed to be killed.
Comment 4 Oleg Khokhlov 2009-09-07 15:11:45 UTC 
I have 2Gb of RAM on my machine and if I run nb with default memory settings I get OOMEs during scanning of this
project. And IDE is still somehow responsible (although slow).
If I set -J-Xmx1024m - it completely hangs after some time and no 'exception' signs in IDE. But in messages.log there
are a lot of exceptions.

Comment 6 David Strupl 2009-09-07 16:18:58 UTC 
The exact steps to reproduce with a fresh checkout of OpenJDK and fresh install of NetBeans would be nice.
Comment 7 Vitezslav Stejskal 2009-09-08 10:10:20 UTC 
Let's wait for Dusan to analyze this. IIRC we used to be able to index openJDK project with -Xmx256m. From your log I
can see that the IDE used -Xmx409m, which IMO should be enough.
Comment 8 Jiri Prox 2009-09-08 14:21:20 UTC 
The OOME is throw also when opening OpenJDK as freefrom project
Comment 9 Jan Lahoda 2009-09-15 11:46:18 UTC 
I was able to open OpenJDK project (jdk/make/netbeans/j2se) with -J-Xmx192m after this patch:
