Comment 1 Martin Entlicher 2005-12-14 09:36:56 UTC 
Thanks for the report. StackFrame.thisObject() can return null in some
circumstances, but the code does not count with that.
Comment 2 Martin Entlicher 2007-12-13 17:14:59 UTC 
Fixed in the new evaluator algorithm - see issue #108873.
Comment 3 Quality Engineering 2010-04-29 09:27:50 UTC 
Verified ... and Closing all issues resolved into NetBeans 6.7 and earlier.
