long story short:
(as mentioned here: http://jogamp.org/jogl/doc/NEWT-Overview.html)

http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/javax/media/opengl/GLAutoDrawable.html#invoke%28boolean,%20javax.media.opengl.GLRunnable%29
http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/javax/media/opengl/GLRunnable.html

Use 'GLAutoDrawable.invoke(GLRunnable)'
[for GLCanvas, GLWindow, ..]

We use this for our graph/UI false color picking algorithm and return false.

The idea is to inject this one shot GL runnable from another thread
not holding the GLContext.

Hope it helps.
