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);
> 	}
> }
