Description ehucka 2007-04-23 14:38:53 UTC 
NetBeans IDE Dev (Build 20070423-0650)
1.6.0; Java HotSpot(TM) Client VM 1.6.0-b105
Linux version 2.6.16-1.2122_FC5 running on i386
en_US (nb); UTF-8

An exception was thrown after show instances on Object[] class. Instances view
was closed before. It was the first call of the action in fresh userdir.
I cannot reproduce it.

Comment 1 Martin Entlicher 2007-04-23 22:03:03 UTC 
This seems to be a profiler issue. Moving to profiler for evaluation.
Comment 2 Jiri Sedlacek 2007-04-23 22:07:19 UTC 
Already fixed in Profiler trunk.
Comment 3 ehucka 2007-04-24 11:20:57 UTC 
NetBeans IDE Dev (Build 20070424-0311)
1.6.0_02-ea; Java HotSpot(TM) Client VM 1.6.0_02-ea-b02
Windows XP version 5.1 running on x86

The NPE was thrown from today's build but it is hard to reproduce. I have seen
it only once.

Comment 4 Jiri Sedlacek 2007-04-24 11:28:28 UTC 
The NPE cannot be thrown from today's build as today's build of the Profiler 
failed due to CVS failure. If you meant NetBeans daily build, then it's 
possible - I've closed this as "Already fixed in Profiler trunk". At the 
Profiler side I cannot do more than just fix it. It's up to you to get Profiler 
trunk and verify it.
Comment 5 ehucka 2007-04-24 12:38:25 UTC 
I am sorry I did not know profiler has still separate cvs. I used continuous
netbeans build.
