java version "1.3.0rc1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0rc1-T)
Java HotSpot(TM) Client VM (build 1.3.0rc1-S, mixed mode)

Although apparently rewritten for RC1 (there is a new class
sun.awt.GlobalCursorManager) mouse-cursor-handling still has some nasty
problems:

- when changing the mouse-cursor of a JFrame to WAIT_CURSOR, while the cursor
  is above a component which has a mouse-cursor set, the mouse-cursor will not
  change visually
- when moving the (successfully changed to WAIT_CURSOR) mouse-cursor outside of
  a JFrame (or to the title-bar or Frame-borders) and back into the JFrame, the
  cursor will be reset

You can use the following program to reproduce these problems:

-------------------- BEGIN
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class WaitCursorTest
{
    private static MouseListener listener = new MouseAdapter(){};
    
    public static void main(String Ps_args[])
    {
        final JFrame F_frame = new JFrame();
        F_frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        F_frame.getContentPane().setLayout(new FlowLayout());

        JButton F_button = new JButton("1 setCursor");
        F_button.setMnemonic('1');
        F_button.addActionListener(new ActionListener(){
            JFrame frame = F_frame;
            public void actionPerformed(ActionEvent e)
            {
                frame.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));

                try
                {
                  Thread.sleep(2000);
                }
                catch (Exception ex)
                {
                }

                frame.setCursor(Cursor.getPredefinedCursor
(Cursor.DEFAULT_CURSOR));
            }
        });
        F_frame.getContentPane().add(F_button);

        F_button = new JButton("2 GlassPane");
        F_button.setMnemonic('2');
        F_button.addActionListener(new ActionListener(){
            JFrame frame = F_frame;
            public void actionPerformed(ActionEvent e)
            {
                JComponent F_gp = (JComponent) frame.getGlassPane();
                F_gp.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
                F_gp.setVisible(true);
                frame.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
                F_gp.addMouseListener(listener);

                try
                {
                  Thread.sleep(2000);
                }
                catch (Exception ex)
                {
                }

                F_gp.removeMouseListener(listener);
                frame.setCursor(Cursor.getPredefinedCursor
(Cursor.DEFAULT_CURSOR));
                F_gp.setCursor(Cursor.getPredefinedCursor
(Cursor.DEFAULT_CURSOR));
                F_gp.setVisible(false);
            }
        });
        F_frame.getContentPane().add(F_button);

        JTextField F_tf = new JTextField("eins");
        F_frame.getContentPane().add(F_tf);

        F_tf = new JTextField("zwei");
        F_tf.setCursor(Cursor.getPredefinedCursor(Cursor.CROSSHAIR_CURSOR));
        F_frame.getContentPane().add(F_tf);

        F_frame.pack();
        F_frame.setVisible(true);
    }
}
-------------------- END

This program displays a JFrame containing 2 JButtons and 2 JTextFields. The
first button uses JFrame.setCursor() to set the mouse-cursor to WAIT_CURSOR,
waits 2 seconds, then resets the mouse-cursor to DEFAULT_CURSOR. The second
button basically does the same, but using the "GlassPane-method" for changing
the mouse-cursor instead (I found this method described here in the JDC some
time ago).

  To reproduce problem 1:
- move the mouse-cursor to one of the JTextFields (mouse-cursor changes to
  TEXT_CURSOR and CROSSHAIR_CURSOR respectively)
- invoke button 1 using its mnemonic (i.e. press ALT-1)

  To reproduce problem 2:
- click button 1 (mouse-cursor changes to WAIT_CURSOR)
- invoke Button 1 using its mnemonic (i.e. press ALT-1)
- move mouse-cursor outside of JFrame and back into it

I believe that these bugs should be fixed in the final JDK1.3!

The bug reported as Bug number 4320939 is NOT fixed even though that
bug was closed as not reproducible in RC2. 

The impact of this bug is that the user cannot tell when a long-running 
operation has completed if he/she moves the cursor out of the Java GUI  window and 
then brings it back . The cursor seems to get reset when it walks 
over the border and often is left as a resize cursor until the Java app restores it to its
original state. It looks very unprofessional.
