NPE when deserializing DefaultListModel

Serializing and deserializing a DefaultListModel does lead to a NPE when a JList gets the deserialized version. The following code does demonstrate that:

---------------------------- Code ---------------

import javax.swing.*;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;
import java.io.*;

public class Test extends JFrame {

public static void main(String[] args) throws IOException

{ final DefaultListModel m1 = new DefaultListModel(); final JList list = new JList(); list.setModel(m1); final XStream x = new XStream(new DomDriver()); x.toXML(m1, new FileWriter("C:/test.xml")); final DefaultListModel m2 = (DefaultListModel) x.fromXML(new FileReader("C:/test.xml")); list.setModel(m2); }

}

----------------------- Output -------------------

Exception in thread "main"

I would appreciate to hear what I can do to get around it.

Thanks
