Bug description:
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)
Caused by: java.lang.NullPointerException
	at net.sourceforge.jnlp.JNLPSplashScreen.correctSize(JNLPSplashScreen.java:71)

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