The JViewport.setViewPosition() throws unexpected NullPointerException

javadoc says: "
public void setViewPosition(Point p)

       Sets the view coordinates that appear in the upper left hand corner of
       the viewport, does nothing if there's no view.
       Parameters:
              p - a Point object giving the upper left coordinates
"
This bug appears in JDK-1.3D
It works correctly in JDK-1.3C.

---------------- example ---------------
public class Test {
 
   public static void main(String argv[]) {
       JViewport c = new JViewport();
       c.add(new JButton());
       c.setViewPosition(new Point(1,1));
       System.out.println("PASSED");

  }
 
}

-------------JDK-1.3D output---------
Exception in thread "main" java.lang.NullPointerException
        at javax.swing.JViewport.setViewPosition(JViewport.java:974)
        at Test.main(Test.java:10)

--- ---------JDK-1.3C output -------------
PASSED
