Method sun.awt.motif.MToolkit.getImage(URL), throws strange Exception (AccessControlException:connect from mars to denied), when tries to get systemresource Image in secure environment (loading applet via http and appletviewer.security.mode=host). Thus many methods in swing classes do not work in this enviroment.


-------------------Example-----------------------------------
import java.awt.swing.*;
import java.applet.*;
import java.net.*;
import java.awt.*;
public class Test1 extends Applet {

  public void init() {

   URL url=UIManager.getLookAndFeel()
                        .getClass().getResource("icons/TreeClosed.gif");
   
   System.out.println("URL:"+url);
   System.out.println("Toolkit:"+Toolkit.getDefaultToolkit());

   Image image = Toolkit.getDefaultToolkit().getImage(url);

  }

}
