javaws throws NullPointerException with some JNLP file

[Jesse]

System: Lucid Beta 1 amd64
I was trying to run Bloom the facebook photo uploader. But OpenJDK's Java Web Start doesn't launch. So I tried it on command line:
$ javaws http://antaki.ca/bloom/Bloom.jnlp
and it dies:

net.sourceforge.jnlp.LaunchException: Fatal: Launch Error: Could not launch JNLP file.
 at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:462)
 at net.sourceforge.jnlp.Launcher$TgThread.run(Launcher.java:731)

Now the workaround: I installed the less free sun-java6-jre and ran update-alternatives to point javaws to sun's version.

i experience the same issue when running an ikvm app from a supermicro server.

please find the logs attached. note: i replaced the server's hostname/ip with "servername".

[Matthias Klose (doko)]

please could you recheck with the openjdk-6 packages in
deb http://ppa.launchpad.net/openjdk/ppa/ubuntu lucid main

I cannot reproduce this crash with these packages

Update from deb http://ppa.launchpad.net/openjdk/ppa/ubuntu lucid main helped me to resolve the problem with the jnlp file from Dell BMC.

still not working for supermicro ikvm with the mentioned sources.

it is, however, working with 10.10 maverick out of the box:

[Raoul Bhatia (raoul-bhatia)]

ok, my bad. java -version clearly shows that i'm using the sun/oracle edition.

using "/usr/lib/jvm/java-6-openjdk/jre/bin/javaws" is still not working:
