profile querying crashes on OS X 10.6 and GMA 950

Hello, I have this following code that used to work on OS X 10.6.8 and GMA 950 hardware (specifically, a 2007 Mac mini) with earlier releases of jogl (it certainly works with RC11, and I think it used to work with some autobuilds after R11):

The code itself is just a simple NEWT-based rendering skeleton that uses NewtCanvasAWT for integration with AWT's frame. Anyways, the error I get when trying to run this project is the following:

java.lang.NullPointerException

, basically when GLProfile.getDefault() is called. Running the same code on another machine with 10.6.8 but with a Geforce 320M yields no errors, so the problem seems to be related to the GMA950. In both cases, the latest official Apple update for Java is already applied (1.6.0_39), and using a recent jogl autobuild from a couple of days ago.

I know that the GMA950 is an aging, fairly limited hardware, but a minor, although still significant, fraction of users on Mac still hold on it, and used to work before, so I wonder if this is a solvable issue. Thanks!

Hi

There is already a bug report about that here. It is probably a bug driver, I can't reproduce it with a Mac Book Pro with an Nvidia chipset under Mac OS X 10.6.8 and Apple Java 1.6.

ok, thanks for pointing out to the bug report.

You're welcome. We should at least find which driver bug causes that crash.

Edit.: Can you remove the glFlush call?
