JPopupMenu not being refreshed properly if overlayed by a JOptionPane on WinNTSP3
Especially the popup part that is under the dialog box is not refreshed

Note that this is the second time i suply this bug since i can't find my first
one in the base. Please in the confirmation mail give the bug id.

The following code shows up the problem :

// Author : Bruno Coudoin
//
// Show evidence that the popup is not refreshed properly under a joptionpane
// Note that if the frame is smaller and the popup goes beyond its limit, then
// the problem do not appear

import javax.swing.*;
import java.util.*;
import java.awt.*;
import java.awt.event.*;

public class refreshBug extends JPanel implements ActionListener {
    JPopupMenu _jPopupMenu = new JPopupMenu();

    public void init() {
JMenuItem menuItem;
JButton jb = new JButton("Bring the popup here and select an item");

this.add(jb, BorderLayout.CENTER);

for(int i=1; i<10; i++) {
menuItem = new JMenuItem("Item "+i);
menuItem.addActionListener(this);
_jPopupMenu.add(menuItem);
}

MouseListener ml = new MouseAdapter() {
public void mouseReleased(MouseEvent e) {
if(e.isPopupTrigger()) {
_jPopupMenu.show(e.getComponent(),
e.getX(), e.getY());
}
}
};
this.addMouseListener(ml);

jb.addMouseListener(ml);

    }

    // An action is requested by the user
    public void actionPerformed(java.awt.event.ActionEvent e) {

JOptionPane.showMessageDialog(this,
"Check if there is some popup left under me\n"+
"if not, retry and let the popup appear where i am",
"WARNING",
JOptionPane.WARNING_MESSAGE);

// Workaround
_jPopupMenu.setVisible(false);
    }

    // Main
    public static void main(String[] args) {
refreshBug applet = new refreshBug();
JFrame frame = new JFrame();

frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});

frame.setTitle("Popup refresh bug");
frame.getContentPane().add(applet, BorderLayout.CENTER);
applet.init();
frame.setSize(400,400);
Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
frame.setLocation((d.width - frame.getSize().width) / 2, (d.height - frame.getSize().height) / 2);
frame.setVisible(true);
    }
