I figured out you must reset the decoration, after you change the L&F,
while the Frame is not realised, like this:

This didn't really work for me. It redrew the frame all right, but I
always got the Windows (my OS) style frame, never the requested L&F.
More work needed I think.

Here's the snippet of Code I changed from John's link. It was pretty
much a blind change, I didn't read through all of Rob Camick's code:

         public void actionPerformed( ActionEvent e )
         {
             try
             {
                 UIManager.setLookAndFeel( laf );
                 defaults.resetComponents();

                 JMenuItem mi = (JMenuItem) e.getSource();
                 JPopupMenu popup = (JPopupMenu) mi.getParent();
                 JRootPane rootPane = SwingUtilities.getRootPane( popup.
                         getInvoker() );
                 SwingUtilities.updateComponentTreeUI( rootPane );

                 JFrame jFrame = frame;
                 System.err.println( "Hacking..." );
                 jFrame.setVisible( false );
                 jFrame.dispose();
                 jFrame.setUndecorated( false );
                 jFrame.getRootPane().setWindowDecorationStyle(
                         JRootPane.NONE );
                 jFrame.setVisible( true );

             } catch( Exception ex )
             {
                 System.out.println( "Failed loading L&F: " + laf );
                 System.out.println( ex );
             }
         }
     }
