ot but need help does gtk+ work with Java 1.4.2_04?

Greetings,

Is there a trick in switching between look and feels?

I could have sworn this used to work. But when I set the Look and Feel to
the new GTK+ parts of the UI appear white. Is there a trick to setting the
Look and Feel. This happens in Linux and Windows.

The Java sample, swingDemo located in the JDK does work correctly but I do
not see what they are doing that I am not.

I can set the Windows XP Look and Feel successfully but the same code does
not work for GTK+. I get part of the UI in white.

I use these two calls:
try {

javax.swing.UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.Window
sLookAndFeel");
            javax.swing.SwingUtilities.updateComponentTreeUI(this);
        }
        catch(Exception e){
            System.out.println("Exception setting look and feel");
        }

and like this:
try {

javax.swing.UIManager.setLookAndFeel("com.sun.java.swing.plaf.gtk.GTKLookAnd
Feel" );
            javax.swing.SwingUtilities.updateComponentTreeUI(this);
        }
        catch(Exception e){
            System.out.println("Exception setting look and feel");
        }

Where the root class is a frame so I am calling these two functions on a
frame assuming that the frame is a container and will update all children.

Thanks in advance and sorry about the Off Topic Post.
