Only one GLContext must be current at a time and the GL object you use must match with the GLContext of the current GLAutoDrawable. I just hope that you don't store any GL instances in fields... Use GLContext.getCurrentGL() and GLContext.getCurrent(), you won't have any trouble or get them from your drawable. I can do nothing more with a SSCCE, a real SSCCE, not a piece of code which might miss the faulty part.
