JCheckBoxMenuItem - border

Question

Hi all,
I have a JMenu.
It has a menu item "JCheckBoxMenuItem".
I can select it. So I can see the check sign. I can also unselect.
But unfortunately the border of the CheckBox (square) does not appear.
I am implementing on XP and using
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
If I comment it out, like
// UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
it works fine, than I can also see the border of the checkbox.
I am using Java version build 1.6.0_05-b13
How can I get it worked?
Thanks
A.

I found a workaround :-)
*1st just create the following file: MyCheckBoxIcon.java*
package menu;
import java.awt.Component;
import java.awt.Graphics;
import java.awt.Polygon;
import javax.swing.Icon;
// Created by Aykut Arslan, 2010-01-03
class MyCheckBoxIcon implements Icon {
    private final int width = 16;
    private final int height = 16;
    private Polygon polygon;
    public MyCheckBoxIcon() {    
      initPolygon();
    private void initPolygon() {
      polygon = new Polygon();
      polygon.addPoint(-width, 0);
      polygon.addPoint(-2, 0);
      polygon.addPoint(-2, height);
      polygon.addPoint(-width, height);
    public int getIconHeight() {
      return width;
    public int getIconWidth() {
      return height;
    public void paintIcon(Component component, Graphics g, int x, int y) {
          g.translate(x, y);
          g.drawPolygon(polygon);
          // following coordination sets the labelposition
          g.translate(-x-width+2, -y);
  }*2nd create the JCheckBoxMenuItem:*
Icon iconBorder = new MyCheckBoxIcon();       
JCheckBoxMenuItem menuItem = new JCheckBoxMenuItem("Menu Item", iconBorder);now you can continue with adding "menuItem" to JMenu etc.
It works :-)
