Cant start the Jenkins webstart JNLP app

[Erik Ramfelt]

I just tried to run the webstart jenkins app (on Meet Jenkins page),
but it wont start and all i get is an exception [1]. I can run other
webstart apps, also I can start the jenkins.war that is referenced in
the JNLP file [2].

Any ideas on what could be wrong or to look into it? Im running Mac OS 10.6.8

Regards
