Problem description
===================
There is an unexpected interdependency between
javax.swing.JComboBox and javax.swing.MenuSelectionManager.
About 120 jck tests, executed in the single JVM fail due to NPE,
thrown by the method javax.swing.plaf.basic.BasicPopupMenuUI$MouseGrabber.grabWindow().

    
Minimized test:
===============
------- Test.java -------
import javax.swing.*;
class Test {
    public static void main(String[] args) {
      JComboBox comboBox = new JComboBox();
      JMenuBar menuBar = new JMenuBar();
      JMenu menu = new JMenu("Menu");
      menuBar.add(menu);
      JMenuItem menuItem = new JMenuItem("Item");
      menu.add(menuItem);
      MenuElement menuPath[] = {menuBar, menu, menuItem };
      MenuSelectionManager.defaultManager().setSelectedPath(menuPath);
    }
}

------- end-of-Test.java -------

======================
