Description Jiri Kovalsky 2012-12-05 17:23:15 UTC 
NetBeans IDE Dev (Build 201212050001) (#115c4cf91d73)
Linux version 3.0.0-12-generic running on amd64

Description:
============
I was working on a simple 1 class Java application. I ran it 3 times, debugged it once and then ran it again twice. Then I opened Favorites view and added a directory with 4 *.class files, 2 *.java files and 1 *.txt file. I opened Hadanka.java into Editor and scrolled down a bit. After a while the OOME occurred.

I can provide both the simple project and mentioned Java file if necessary.
Comment 1 Jiri Kovalsky 2012-12-05 17:30:33 UTC 
Heap dump was provided off-line to Tomas Hurka.
Comment 2 Jiri Kovalsky 2012-12-05 17:48:26 UTC 
Created attachment 128919 [details]
Hadanka.java file 100% reproducing the OOME.

Further investigation showed that it's enough just to open this Hadanka.java file and after few seconds the IDE becomes unresponsive.
Comment 3 Tomas Hurka 2012-12-05 22:10:44 UTC 
Heap dump is available at <http://netbeans.org/projects/profiler/downloads/download/Heapdumps/heapdump-223339.zip>
Comment 4 Tomas Hurka 2012-12-06 08:58:59 UTC 
Reassigning to java/hints. 90% of the heap is retained by org.netbeans.modules.java.hints.bugs.NPECheck$VisitorImpl#1 842,121,908 (90.7%)
Comment 5 Quality Engineering 2012-12-07 02:40:52 UTC
