I've got an applet that uses JOGL. It works fine the first time you load the page. But if you click the browser's "back" button and then press "forward" soon after, I get the following exception:

javax.media.opengl.GLException: Shared Surface not ready (lockSurface):

I've only seen this since upgrading to JOGL 2.0.

Has anyone seen and solved this? I don't know if this is a bug in my code -- i.e., I'm not calling a proper shutdown method -- or a JOGL bug.
