[classlib][x-management]javax.management.relation.MBeanServerNotificationFilter.isNotificationEnabled(null)
 throws NPE instead of IllegalArgumentException
-----------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-1731
                 URL: http://issues.apache.org/jira/browse/HARMONY-1731
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Nikolay Bannikov


Description: 
According to J2SE API specifications the method must throw IllegalArgumentException - if null
parameter.
RI throws it while Harmony does not.

Test for reproducing:   
import junit.framework.TestCase;
import javax.management.relation.MBeanServerNotificationFilter;

public class Test extends TestCase {       
    public void testMBeanServerNotificationFilter_isNotificationEnabled() {
        MBeanServerNotificationFilter c = new MBeanServerNotificationFilter();
        try {
                  c.isNotificationEnabled(null);
        } catch ( IllegalArgumentException e) {
                  //expected
        } catch ( NullPointerException ne) {
                  fail("NPE shouldn't be thrown");
        }
    }
}
