Jan, can you please have a look at this? I am passing this to you since you fixed the very similar bug 193545. Thanks for looking at this one as well.
Comment 4 Jan Lahoda 2011-01-07 10:44:45 UTC 
The original fix was not defensive enough, lets try this:
http://hg.netbeans.org/jet-main/rev/d04fa0ce123c
Comment 5 Quality Engineering 2011-01-09 06:20:45 UTC 
Integrated into 'main-golden', will be available in build *201101090000* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
Changeset: http://hg.netbeans.org/main/rev/d04fa0ce123c
