This is the SwingSet2 demo running on JNode with the integrated Swing implementation of OpenJDK. Currently the JNode desktop is based on the Swing JDesktopPane and the JFrame peer is based on JInternalFrame. Therefor SwingSet2 is running on a purely Swing based desktop. More work is needed on the Swing based AWT peers and better Java2D support but I will commit the code soon which makes the above demo possible.
It looks like we can anticipate a really interesting JNode release this summer. : -)
