I have some code to add animated GIFs to a JTextPane but unfortunately they
come out corrupted.  Can anybody tell me how to solve this?  I have added
the smallest code that exhibits this behaviour below.

Thanks
Allan

import java.net.URL;
import javax.swing.*;

public class EmotTester
{
   public EmotTester()
   {
       JFrame lFrame = new JFrame("Test");
       JTextPane lTP = new JTextPane();
       lFrame.getContentPane().add(lTP);
       lFrame.pack();
       lFrame.setVisible(true);
       lFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

       try
       {
           URL lFileURL = this.getClass().getResource("test.gif");
           lTP.insertIcon(new ImageIcon(lFileURL));
       }
       catch (Exception e)
       {
           System.out.println("Exception: " + e);
       }
   }

   public static void main(String [] args)
   {
       new EmotTester();
   }
}
