Using JPopupMenu in heavyweight mode (setLightWeightPopupEnabled(false))
results in the inability of the menu to display its submenus over a
JFrame.

Steps to reproduce:

1. Create a JPopupMenu and call setLightWeightPopupEnabled(false)
   on the popup.
2. Add several JMenus to the popup each containing at least 1
   item.
3. Invoke the popup in a JFrame.
4. Notice that the popup doesen't display any of the submenus.

If the popup is displayed outside of the frame the submenus
will display properly.

Example code:

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

public class HeavyPop implements ActionListener
{
    JPopupMenu popup;
    JButton btn;
    JFrame frame;
    JPanel panel;
    JMenu menu;

    public static void main(String args[])
    {
        HeavyPop hp = new HeavyPop();
        hp.display();
    }
    public void display()
    {
        frame = new JFrame();
        panel = new JPanel();
        btn = new JButton("Test");
        btn.addActionListener(this);
        popup = new JPopupMenu();
        popup.setLightWeightPopupEnabled(false);
        for (int i=0; i<5; i++)
        {
            menu = new JMenu("menu " + i);
            menu.add("item " + i);
            menu.getPopupMenu().setLightWeightPopupEnabled(false);
            popup.add(menu);
        }

        panel.add(btn);
        frame.getContentPane().add(panel);
        frame.setSize(600,400);
        frame.setVisible(true);
    }
    public void actionPerformed(ActionEvent e)
    {
        popup.show(btn,btn.getWidth(),0);
    }
}
