Actually, I'm almost sure that it's not really a bug. When you don't use an animator, you have to call GLAutoDrawable.display().

Call GLAutoDrawable.display() when its container is ready to be displayed the very first time and use a ComponentListener to detect when the canvas is resized and call GLAutoDrawable.display()... or use an animator in order to let JOGL take care of calling GLAutoDrawable.display() for you. It depends on the level of control you need, both options make sense.
