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:

, 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!
