Primeira vez usando o Java Web Start no Ubuntu - Fatal Launch Exception

Question

Estou usando o Ubuntu há algum tempo e os aplicativos Java Web Start nunca "funcionaram" na versão atual ou em qualquer versão anterior, então os ignorei até agora. No entanto, agora tenho a necessidade de fazê-los funcionar no Firefox. Quando estou em uma página como esta: link Quero ser capaz de clicar nas demos conforme sugerido e executá-las.

Estou executando o Ubuntu 11.10 com o Gnome 3 e / ou o Linux Mint 12 (64 bits) com o OpenJDK 6, OpenJDK 7 e Sun Java 6. Meu padrão é atualmente: / usr / lib / jvm / java-6-openjdk / jre / bin / java

$ where javaws
javaws: / usr / bin / javaws

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

Aqui está o erro que recebo quando tento executar um aplicativo Java Web Start:

RESOLVIDO: Aparentemente, o java Java Sun funciona. No Firefox:
