XMLEncoder on java 1.5.0 no serialize minimumSize property

Question

Hi,
XMLEncoder on java 1.5.0 no serialize minimumSize, preferredSize and maximumSize properties!
Exemple with outputs on java 1.4.2_04 and 1.5.0:
import javax.swing.JButton;
import java.beans.XMLEncoder;
import java.awt.Dimension;
public class SerializeMinimumSize
{  public static void main(String[] args)
   {  XMLEncoder enc = new XMLEncoder(System.out);
      JButton btt = new JButton("miao!");
      btt.setMinimumSize(new Dimension(32,64));
      enc.writeObject(btt);
      enc.close();
}With 1.4.2_04:
<?xml version="1.0" encoding="UTF-8"?>
<java version="1.4.2_04" class="java.beans.XMLDecoder">
<object class="javax.swing.JButton">
  <string>miao!</string>
  <void property="minimumSize">
   <object class="java.awt.Dimension">
    <int>32</int>
    <int>64</int>
   </object>
  </void>
</object>
</java>With 1.5.0:
<?xml version="1.0" encoding="UTF-8"?>
<java version="1.5.0" class="java.beans.XMLDecoder">
<object class="javax.swing.JButton">
  <string>miao!</string>
</object>
</java>Omit the property minimumSize, why?

I've found the soluction in java.bean.Metadata source... ~
I've created my PersistenceDelegate for my component. Is more simple that it may appear!
bye!
