Description _ tboudreau 2009-09-29 23:47:24 UTC 
Mac OS, JDK 6, build 200909221401:  Create a new JPanel form (in my case, in a standalone module project).  Right click the panel's node in the Inspector 
and choose Set Layout > GridBagLayout (or FlowLayout or others).  A dialog pops up saying the layout cannot be initialized, and the exception below is 
thrown:

Comment 1 pribyl 2009-09-30 09:18:47 UTC 
Cannot reproduce on Windows (JDK 1.6_06). Seems to be MacOs specific...
Comment 2 Tomas Pavek 2009-09-30 18:23:45 UTC 
Yes, Mac JDK 6 specific.
Hopefully fixed.
