Launcher Hangs On Startup

This issue started appearing yesterday.

 

When trying to launch wurm I get the following output:

And the program hangs forever. I have tried launching from firefox and downloading a new .jnlp, with no success.

Problem was solved by installing Oracle java instead of icedtea.
