[classlib][swing] javax.swing.plaf.basic.BasicMenuItemUI.uninstallUI(new JOptionPane()) throws
unspecified NPE while RI throws ClassCastException
-------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-2704
                 URL: http://issues.apache.org/jira/browse/HARMONY-2704
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Alexander Simbirtsev


There is no mention of any exception in the specification.
Harmony throws unspecified NPE for uninstallUI(new JOptionPane()) while RI
throws ClassCastException

Use the following code to reproduce:

import javax.swing.JOptionPane;
import javax.swing.plaf.basic.BasicMenuItemUI;

import junit.framework.TestCase;

public class Test extends TestCase {
    public void testcase1() {                                    
        try {
            BasicMenuItemUI bm = new BasicMenuItemUI();
            bm.uninstallUI(new JOptionPane());
        } catch (NullPointerException e) {
            fail("NPE thrown");
        } catch (ClassCastException e) {
            // expected
        }
    }
}

Seems like RI uses the parameter passed to this method while Harmony uses member variable
menuItem within this method
