Hi guys.  Major problem:

Have a JOGL app that runs great with the last Apple JRE 6 and breaks with newest Oracle JRE 7.  Tried both  rc11 and rc10 of JOGL.  

Symptom is that a GLCanvas animation in the Swing app refreshes only about 4 frames per second even though the app says it's rendering at 38.  Then when the animation is turned off with the GUI, which causes GLCanvas.setVisible(false) internally, GUI hangs, though no exception is raised.

MacBook Pro, 15-inch, Late 2008
2.8 GHz Intel Core 2 Duo
OS X 10.8.2 (12C60)
NVIDIA GeForce 9400M 256 MB

This is a major production problem for an app with many thousands of users. For the time being I will either have to bundle it with JRE 6, which triples the download package size, or junk the JOGL animation feature which will make many people unhappy.

Before I try to cook up a small example for a bug report, is this a known issue?  Workaround?

I am guessing maybe Oracle had to use the OpenGL rendering pipeline for Java 2D because Apple didn't give them the one for Quartz, and this is conflicting with JOGL?  I can find zero info on the web about how Oracle Java 7 is rendering Java 2D on Mac OS X.

Thanks for your help.  I'm really against the wall with a ship date 9 days from now.
