Description rstaff 2009-07-22 14:38:50 UTC
Build: NetBeans IDE 6.5 (Build 200811100001)
VM: Java HotSpot(TM) Client VM, 14.0-b16, Java(TM) SE Runtime Environment, 1.6.0_14-b08
OS: Linux, 2.6.24-2009-06-15, i386

User Comments:
rstaff: Somehow a window to attach a debugger popped up several times when the IDE was loading while I was in another application and then an NPE occurred.  Clicking the cancel button would not close the dialog, although the close button worked.

Happened just once under a special occasion -> P4.
Comment 3 Martin Entlicher 2009-09-10 15:43:30 UTC
dialog is null, you've probably managed to press the OK/Cancel button twice before the dialog managed to close itself.
