There is no version 2.3.2 yet. Please provide a test case to reproduce your bug. X11ExternalGLXContext$Drawable.getSurfaceWidth() shouldn't be called directly, this kind of drawable is used internally just to provide a display connection. Maybe the problem comes from your wrapper around GLContext. Rather use GLContext.getCurrentGL(). I already worked on a similar platform based on Eclipse RCP and SWT with JOGL, I had to port my own code from JOGL 1.1.1a to JOGL 2.0. I have to look a bit deeper at your code.
