[classlib][swing] Can not move window showing popupMenu

                 Key: HARMONY-5060
                 URL: https://issues.apache.org/jira/browse/HARMONY-5060
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
         Environment: Win32
            Reporter: Chunrong Lai

 Below is the simple reproducer.
 I only succeed in the first time when I try to move the window with the PopupMenu showing.
After that I can not move the window if the popup menu is shown. After some tracing I see
that the window can be moved because the WM_CAPTURECHANGED event is generated and handled.
But generally there are only MOUSE_PRESSED events instead of the WM_CAPTURECHANGED event.

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

public class PopupMenuDemo extends JPanel {
    public PopupMenuDemo() {
        super(new BorderLayout());

        String[] theStrings = { "First", "Second", "Third", "Fourth" };
        JComboBox theList = new JComboBox(theStrings);
        add(theList, BorderLayout.PAGE_START);

    public static void main(String[] args) {
        JFrame frame = new JFrame("PopupMenuDemo");

        JComponent newContentPane = new PopupMenuDemo();
        newContentPane.setOpaque(true); //content panes must be opaque

        frame.setBounds(100, 100, 200, 50);
        //Display the window.
