Java WebStart doesn't work under OpenJDK 6 (java.lang.NoSuchMethodException JOSM.main)

Under Ubuntu 8.10:

avar@aoeu:~$ /usr/lib/jvm/java-6-openjdk/jre/bin/javaws http://josm.openstreetmap.de/download/josm.jnlp
netx: Launch Error: Could not launch JNLP file. (java.lang.NoSuchMethodException JOSM.main([Ljava.lang.String;))

Using Sun Java 6 works however.

Interesting! I have the same "problem". But if I click "webstart" on the mainpage of josm here it works.

This is/was a known issue and apparently a bugfix has been checked in and pushed for Fedora. Hopefully other distributions catch up soon and WebStart will work for many.
