A DESCRIPTION OF THE PROBLEM :
when moving a JInternalFrame withing a JDesktopPane with
outline drag mode set, the MouseListeners within the
"moving" frame are excited when you, say, pass the mouse
over the position where the component "used to" be.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. run the code below
2. bring mouse in from north side
3. drag frame south, you should see the JTextField update
even though you're not hovering over the JButton.


EXPECTED VERSUS ACTUAL BEHAVIOR :
expected to work like normal drag mode under JDesktopPane,
which doesn't pass the events through when moving the frame.

This bug can be reproduced always.

public class Example extends JDesktopPane {

    static public void main(String args[]) {
        JFrame jf = new JFrame("example");
        jf.setContentPane(new Example());
        jf.pack();
        jf.show();
    }

    public Example() {
        setPreferredSize(new Dimension(400, 400));
        setDragMode(OUTLINE_DRAG_MODE);
        addFrameWithMouseListener();
    }

    void addFrameWithMouseListener() {
        JInternalFrame jif = new JInternalFrame("listen!");
        
        JPanel jp = new JPanel(new BorderLayout(2,2));
        
        final JTextField info = new JTextField(30);
        jp.add(info);

        JButton jb = new JButton("component with a listener");
        jb.addMouseListener(new MouseAdapter() {
                public void mouseEntered(MouseEvent e) {
                    info.setText("ran over button");
                }
            });
        jp.add(jb, BorderLayout.NORTH);

        jif.setContentPane(jp);
        jif.pack();
        jif.setLocation(new Point(10, 200));
        add(jif);
        jif.setVisible(true);
