Description skesper 2004-08-27 10:52:02 UTC

[ BUILD # : Beta 1 ]
[ JDK VERSION : J2SE 1.5.0 ]

I'm not pretty sure that this is a bug. But when I had a lot of programs (jvm's) running I ran out of virtual memory on my windows XP platform. I stoped the programs and shutdown netbeans. After that I changed my netbeans.conf -J-Xms128m parameter to -J-Xms25m. And then restarted netbeans. 

Since that I'm getting the ArrayIndexOutOfBoundsException every time I start netbeans.

Now I get it allways. Even after I've installed a new build [200408291800]
But the stack trace has changed a bit:

Comment 2 Petr Hrebejk 2004-09-07 14:22:11 UTC

Replaced by safer implementation. Should not happen again. 

(For the reporter: seems that you have some broken project - may be
because of the OOME - which does not list it's project dir among its
source groups. You might need to recreate the project)

Checking in
projects/projectui/src/org/netbeans/modules/project/ui/PhysicalView.java;
/cvs/projects/projectui/src/org/netbeans/modules/project/ui/PhysicalView.java,v
 <--  PhysicalView.java
new revision: 1.10; previous revision: 1.9
done

Comment 3 Marian Mirilovic 2005-12-20 15:49:39 UTC

This issue was solved long time ago. Because nobody has reopened it neither
added comments, we are verifying/closing it now. 
If you are still able to reproduce the problem, please reopen. Thanks in advance.
