javaws doesn't open Supermicro remote console (IP-KVM)

[Alexander List]

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:

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.

The problem doesn't surface when I use the Oracle JDK, Java(TM) Web Start 10.11.2.21-fcs.

I'm getting this error too with 12.10. I think this is regression because it worked in 12.04 for me and it doesn't in 12.10

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

I'm still getting this on 12.04.2 (64bits).

I just found 2 bug reports at RedHat which sound like they could be related to this:

https://bugzilla.redhat.com/show_bug.cgi?id=675271
duplicate of:
https://bugzilla.redhat.com/show_bug.cgi?id=753960

Which is marked as fixed in Fedora's "icedtea-web-1.3-1.fc17.0.x86_64" package.

Still the case on 14.04 LTS. In Xenial, icedtea-8 works.
