So I got it to work by changing my AutoDrawable to be:

            GLWindow glWindow = GLWindow.create(glCaps);

Instead of:

        GLDrawableFactory factory = GLDrawableFactory.getFactory(glProfile);
        GLAutoDrawable drawable = factory.createOffscreenAutoDrawable(null, glCaps, null, _width, _height);

The "Upstream Widget" for GLWindow is NEWT. For the second it is null. And while it works now, I have a bogus onscreen window for every offscreen AutoDrawable that I would have to hide somehow.

Any idea why it works for GLWindow and not GLDrawableFactory.createOffscreenAutoDrawable()?
