I have tried starting wija, an XMPP messaging client, with libgcj7-1-awt on
Ubuntu 7.10.
How to reproduce:

1) Download wija-change1363.zip from http://www2.media-art-online.org/nightly/
2) Unzip the file, and remove from "plugins" directory the following two files:
  * org.media_art_online.circ.Circ.jar
  * org.media_art_online.circ.Circ.jar.sig
  as they would cause another problem on a MIDI device.
3) start wija by the command: java -jar wija.jar
4) Ignore all setting up, and log in using an existing Jabber ID.
  This would generate the following exception:

Exception in thread "Thread-48" java.lang.NullPointerException    at
javax.swing.JTree.removeDescendantSelectedPaths(JTree.java:3085)    at
javax.swing.JTree$TreeModelHandler.treeStructureChanged(JTree.java:1299)    at

org.media_art_online.wija.WijaUI.showRoster(WijaUI.java:1236)    at

If you try logging in with a jabber.org ID, do not specify SSL (there is a
problem with the certificate).
If you use Gmail/Google Talk ID, specify gmail.com as the domain, and do
specify SSL (although this might cause another problem).
