Comment 1 Jesse Glick 2008-08-21 01:00:39 UTC 
No clue how to reproduce. Sounds like some kind of corruption in the installation.
Comment 2 Exceptions Reporter 2008-10-06 20:08:02 UTC

50 duplicates, all on Windows machines..
Comment 4 Jesse Glick 2008-11-07 17:55:20 UTC 
Unfortunate that it happens a lot, but I have no way to reproduce, nor any clue what might be wrong except that the
installation may be corrupt. core-main #e4a7e3f68e1c might produce more useful diagnostic info, or it might not.
Comment 5 Quality Engineering 2008-11-08 04:30:21 UTC 
Integrated into 'main-golden', will be available in build *200811080201* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
Changeset: http://hg.netbeans.org/main/rev/e4a7e3f68e1c
User: Jesse Glick <jglick@netbeans.org>
Log: Trying to diagnose #143648.
Comment 6 Jesse Glick 2008-11-10 22:18:31 UTC 
Related code was just changed significantly in #b67c171c7f6a, which might fix this problem as a side effect, or not.
Still no clue what causes this.
Comment 7 Jesse Glick 2008-11-19 00:31:27 UTC 
Closing for now. If it reappears in new dev builds, can try again to add diagnostics.
