Subject [jira] Created: (HARMONY-1812) javax.swing.plaf.basic.BasicTableHeaderUI.MouseInputHandler.mouseEntered(MouseEvent e) throws unspecified NPE while RI does not

javax.swing.plaf.basic.BasicTableHeaderUI.MouseInputHandler.mouseEntered(MouseEvent e) throws
unspecified NPE while RI does not
-------------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-1812
                 URL: http://issues.apache.org/jira/browse/HARMONY-1812
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Vera Aristova
            Priority: Minor


javax.swing.plaf.basic.BasicTableHeaderUI.MouseInputHandler.mouseEntered(MouseEvent e) throws
unspecified NPE when e is null while RI does not throw it. It's a compatibility issue.
Test for reproducing:
import junit.framework.TestCase;
import javax.swing.plaf.basic.BasicTableHeaderUI;

public class TestBasicTableHeaderUI_MouseInputHandler	extends	TestCase {
	public void testMouseEntered() 
	{
		BasicTableHeaderUI localBasicTableHeaderUI = new BasicTableHeaderUI();
		BasicTableHeaderUI.MouseInputHandler ui = localBasicTableHeaderUI.new MouseInputHandler();
		ui.mouseEntered(null);
	}
}
