It works fine for me on Linux with JDK 1.5 and a latest build of NetBeans. Can you please verify again ?
Comment 2 twleung 2009-06-29 18:41:05 UTC 
I was able to reproduce this on my machine.  Mac OS 10.5.7, JDK 1.6
Comment 3 amitksaha 2009-06-30 06:56:53 UTC 
Thank You Ted for verifying. Linux and Solaris works fine. If anyone could test Windows, then I could classify it as a
MacOSX Bug.
Comment 4 amitksaha 2009-07-07 11:55:58 UTC 
Seems to be a MacOSX Issue. I do not have a Mac at my disposal, hence I can't look into it.
