I'm using this code to init a GLWindow:

        private void initGLWindow()
        {
                glWindow = GLWindow.create(caps);
                glWindow.setTitle(name);
                glWindow.setSize(sizeX, sizeY);
                glWindow.setAutoSwapBufferMode(true);
                glWindow.addGLEventListener(this);
                glWindow.setVisible(true);
        }

Pretty straightforward stuff, however when setVisible(true) is called, it suddenly throws a NullPointerException. Why does this happen? All the other calls succeeded, so it's weird that only that last call yields an exception, right?

Thanks for the help!

EDIT: While I'm asking questions: Is it possible to make a GLWindow non-resizable? I've looked through the documentation, but I couldn't find anything.
