Since Java 6, there is build-in systray support for all Java-enabled platforms. This works fine in KDE and Gnome, but inside XFCE Java says there is no systray support available. A simple 'java.awt.SystemTray.isSupported()' invocation returns 'false', ignoring this don't helps ;)
4.2, 4.4, trunk? If you're not using trunk, please try the system tray in trunk.

Could you try the trunk version of xfce panel?
Here is the latest verion of the panel in a tarball: http://foo-projects.org/~nick/packages/xfce4-panel-4.5.0.3svn-r26381.tar.bz2
This is a bug in old versions of Java itself and cannot be properly fixed in xfce. See http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6438179 and please retry with the new Java update.
Java bug, not us.
