I overlooked a missing piece in your init method as well. You need to set the view port. Add something along the lines of this to the end of init():

    final GL4 gl = arg0.getGL().getGL2();
    gl.glViewport(0, 0, arg0.getWidth(), arg0.getHeight());

If that doesn't get you going:

• Take a look at the rest of my init method to see if any of the other differences are significant.
• Set some breakpoints in your display(), init(), dispose(), and reshape() methods
• Do all the values of your member variables make sense (i.e. does it look like everything was initialized as expected)?
• Are any of the methods called when you don't expect them to be?
