Description Nazmul Alam 2012-11-06 10:03:34 CET
I used jogl 1.1 until now for our application without any error. But since I have updated my code to adapt jogl 2 it gives some unexpected random NullPointerException. Sometimes it works fine sometime it doesn't. I have tried to debug but found no error. and it happens only with my application. I have tried the jogl examples but those works fine. One difference is I use GLUtessellator and the examples doesn't. And ofcourse the error occurs at beginData(int type, Object data) in GLUtessellatorCallback. I guess that it might be a problem with the mismatch of variable 'type'. Since the error occurs randomly, I am not sure if exactly this is the problem but I guess once i noticed the value of 'type' was not as expected and that caused the error.

Thanx in advance.
