Description _ pcw 2006-06-01 01:54:15 UTC 
I was using NetBeans instance A to debug NetBeans instance B.  B was started at
the console with server=y,suspend=n.

I attached A while B was starting up.  I detached A while B was still starting
up (ie my system was a bit sluggish).  At the point where I detached, the
debugger UI had been displayed (windows, breakpoints, etc.), but the "attaching
debugger" progress display was still active.

I immediately received this exception in the debugger instance of NetBeans:

java.lang.NullPointerException

Comment 1 Martin Entlicher 2006-06-28 13:29:14 UTC 
It's caused by the fact that the debugger has finished before it fully started.
There need to be some checks or synchronizations....
Comment 2 Martin Entlicher 2007-01-08 16:10:16 UTC 
This is a duplicate of issue #88247. It's already fixed in trunk.

Verified ... and Closing all issues resolved into NetBeans 6.7 and earlier.
