If it can help you, i saw many windows with apparently the same 
error. Anyway, a nullpointerexception. This errors came back when i 
restarted NetBeans. 

I am using the version 4.0 beta 1. 
The VM is 1.5.0 rc-b63
Product version NetBeans IDE dev (build 200408191352)
IdeVersionning IDE/1 spec=4.43 impl=200408191352

Good luck and thank you

The problem is that the metadata storage got corrupted. We had many
problems causing this in beta1 - these are now fixed. Please upgrade
to 4.0 release or the recent q-build of 4.1 to fix the problem.
