Try changing the demos to use the GLEventListener model (if they
aren't already) and setUseRepaint(false) on the GLAnimCanvas.
This should prevent multithreaded use of the OpenGL context via
the internal "enableAWTThreadRendering" flag. If this fixes the
crash, there is either a bug in NVidia's drivers with respect to
multithreading or there is a threading bug in GL4Java. NVidia
employees tend to frequent the OpenGL discussion forums:
