ChangeEvent fires when mouse enters or exits JCheckBox

Java HotSpot(TM) Client VM (build 1.3.0), mixed mode

When the code below is run under linux JVM 1.2.2 moving the mouse in and out of
the JCheckBox will not fire a ChangeEvent. When run under linux JVM 1.3
ChangeEvents are fired when the mouse enters or exits the JCheckBox. The
ChangeEvent is also fired under the Windows 1.3.0 JVM (no Windows 1.2.2 JVM to
check against -sorry).

This may be a problem with 1.2.2 or 1.3, i'm unsure whether sun intended to
fire the event or not.

// Code to check for ChangeEvents
public class CheckBoxEvents extends Object {

    public static void main(String[] argv) {
        JCheckBox cb = new JCheckBox("Roll mouse over me");

        cb.addChangeListener( new ChangeListener () {
            public void stateChanged(ChangeEvent e1) {
                System.out.println("Change Event Caught");
            }
        });

        JFrame f = new JFrame();
        //f.addWindowListener(new BasicWindowMonitor() );
        Container c = f.getContentPane();
        c.add(cb);
        f.pack();
        f.setVisible(true);
    }

}
