      XMLEncoder miss write out javabean property of Point on JDK1.6.0-beta2,other JDK version 1.4 and 1.5 is ok.

      REGRESSION. Last worked in version mustang

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      import java.awt.Point;

      public class MyBean {

      // if change code to: Point location = null.
      // location information can be write out in xml.
          Point location = new Point();
       
          public Point getLocation() {
           return location;
          }

          public void setLocation(Point location) {
           this.location = location;
          }

      }

        XMLEncoder e = new XMLEncoder(new BufferedOutputStream(
          new FileOutputStream("c:/Test.xml")));

        e.writeObject(bean);
        e.close();

        XMLDecoder d = new XMLDecoder(new BufferedInputStream(
          new FileInputStream("c:/Test.xml")));
        
        System.out.println(((MyBean)d.readObject()).getLocation());
        d.close();

       }
