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);
    }

N/A

Same as bug ID 4189244

I ran into this bug, and I found a workaround:  
After the dialog is dismissed, call repaint() on 
the JFrame that contains the menu bar.  
(Actually, I call repaint() on both the JFrame and 
its contentPane (see JFrame.getContentPane()).  
I'm not sure if both repaints are necessary, or 
which one  of them is the one that does the 
trick.)
