Comment 13 for bug 224800

Openjdk works well in karmic indeed but Sun Java webstart gives me this:
~$ javaws http://sweethome3d.sourceforge.net/SweetHome3D.jnlp
net.sourceforge.jnlp.LaunchException: Fatal: Launch Error: Could not launch JNLP file.
 at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:447)
 at net.sourceforge.jnlp.Launcher$TgThread.run(Launcher.java:714)
Caused by: java.lang.NullPointerException

Caused by:
java.lang.NullPointerException

Has anyone the same problem?
