Première utilisation de Java Web Start dans Ubuntu - Exception de lancement fatal

Cela fait un moment que j'utilise Ubuntu et Java les applications Web Start n'ont jamais "fonctionné" dans la version actuelle ou antérieure, et je les ai donc ignorées jusqu'à présent. Cependant, j'ai maintenant besoin de les faire fonctionner dans Firefox. Quand je suis sur une page comme celle-ci: http://www.Oracle.com/technetwork/Java/demos-nojavascript-137100.html Je veux pouvoir cliquer sur les démos comme suggéré et faites-les courir.

J'utilise Ubuntu 11.10 avec Gnome 3 et/ou Linux Mint 12 (64 bits) avec OpenJDK 6, OpenJDK 7 et Sun Java 6. Mon fichier par défaut est actuellement:/usr/lib/jvm/Java- 6-openjdk/jre/bin/Java

$ whereis javaws
javaws:/usr/bin/javaws

/ etc/alternatives/javaws ->/usr/lib/jvm/Java-6-openjdk/jre/bin/javaws

Voici l'erreur que j'obtiens lorsque j'essaie d'exécuter une application Java Web Start:
