Public bug reported:

When trying to open the IP-KVM (remote console) of my Supermicro X9SCM-F
mainboard, I get an error:

net.sourceforge.jnlp.LaunchException: Fatal: Initialization Error: Could not 
initialize application.

This is reported against Fedora as well:

https://bugzilla.redhat.com/show_bug.cgi?id=753960

No difference between openjdk-6 and openjdk-7.

I expect this to work on Ubuntu, just like Dell DRAC, HP ILOM, IBM ...
remote IPMI/IP KVM.

The JNLP file was downloaded using Chromium, invocation of javaws was
from the shell, but that makes no difference.
