We require some additional information, please read:
http://jogamp.org/wiki/index.php/Jogl_FAQ#Bugreports_.26_TestingAlso the complete sourcecode for your example would be needed since we do not know which caps you use and on which hardware + driver combination you test on.
Please include the stacktrace for the nullpointer exception, since we cant possibly guess.
