Java AWT Move mouse automatically without triggering MouseMotionListener

I'm making a game with JOGL. I made a GLJPanel, and got everything set up. However, I have trouble with the camera rotation. Here's my mouse listener:

        panel3D.addMouseMotionListener(new MouseMotionAdapter() {
            final int[] pos = new int[]{panel3D.getLocationOnScreen().x + panel3D.getWidth() / 2, panel3D.getLocationOnScreen().y + panel3D.getHeight() / 2};

            @Override
            public void mouseMoved(MouseEvent e) {
                panel3D.rot[0] += e.getX() - pos[0];
                panel3D.rot[1] += e.getY() - pos[1];
                pos[0] = e.getX();
                pos[1] = e.getY();

                panel3D.rot[1] %= 90;

                try {
                    Point point = panel3D.getLocationOnScreen();
                    new Robot().mouseMove(point.x + panel3D.getWidth() / 2, point.y + panel3D.getHeight() / 2);
                } catch (AWTException ex) {
                    throw new RuntimeException(ex);
                }
            }
        });

        panel3D.addMouseMotionListener(new MouseMotionAdapter() {
            final int[] pos = new int[]{panel3D.getLocationOnScreen().x + panel3D.getWidth() / 2, panel3D.getLocationOnScreen().y + panel3D.getHeight() / 2};

            @Override
            public void mouseMoved(MouseEvent e) {
                panel3D.rot[0] += e.getX() - pos[0];
                panel3D.rot[1] += e.getY() - pos[1];
                pos[0] = e.getX();
                pos[1] = e.getY();

                panel3D.rot[1] %= 90;

                try {
                    Point point = panel3D.getLocationOnScreen();
                    new Robot().mouseMove(point.x + panel3D.getWidth() / 2, point.y + panel3D.getHeight() / 2);
                } catch (AWTException ex) {
                    throw new RuntimeException(ex);
                }
            }
        });

As you can see, it should work fine. However, the Robot class re-calls this MML with inverted mouse X and Y, so the camera just snaps back with the mouse. Is there a way to fix this?
