Bug 664

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

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.  Additionally, the VM image of the app starts growing rapidly as soon as the GLCanvas is shown and keeps growing quickly.

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

JRE that works:
Java for Mac OS X (1.6.0_37-b06-434)

JRE that fails:
Java SE 1.7.0_10

I am guessing maybe Oracle had to use the OpenGL rendering pipeline for Java 2D because Apple didn't give them the Quartz pipeline, 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. I thought maybe fiddling with the rendering pipeline as you can with Windows and Linux might make a difference.

Below is the smallest useful example I can come up with.  Pressing the button should switch back and forth between a normal Swing JPanel with some text and the GLCanvas with a white square rotating smoothly on a black background.

With Java 6 it's fine.  With Java 7, the animation is not smooth (though it's much better than my full app with >30,000 triangles).  And when you press the button the second time, the text card does not reappear (GLCanvas setVisibility(false) is failing), and the VM image starts growing very quickly thereafter.

All help greatly appreciated.
