Hi

The NullPointerException comes from your own code:
Caused by: java.lang.NullPointerException
        at webgps.graphics.FastRingsAnimator.drawDefault(FastRingsAnimator.java:546)

Please provide a small test case if you really think that it's caused by a regression in JOGL itself.

Edit.: Please use JOGL 2.3.0 which isn't the case according to your stack trace that still mentions the package "javax.media.opengl" absent of the very latest version. The AWT GLCanvas is now in com.jogamp.opengl.awt:
