How to reproduce ? Unit test ?
Comment 2 Sven Gothel 2013-07-17 03:38:35 CEST 
git tip doesn't match stack trace, hence I don't know where it happens - no git sha1 given!

also: pls add reproduction test case etc.

pls reopen if bug still exists and you are willing/able to provide details,
see wiki/jogl/faq/bugreport.
