Ubuntu에서 Java Web Start를 처음 사용하는 경우-치명적인 실행 예외

한동안 우분투를 사용 해왔고 Java Web Start 응용 프로그램은 현재 또는 이전 버전에서 "단지 작동"한 적이 없었기 때문에 지금까지 무시했습니다. 그러나 이제 Firefox에서 작동하도록해야합니다. 다음과 같은 페이지에있을 때 http://www.oracle.com/technetwork/java/demos-nojavascript-137100.html 제안 된 데모를 클릭하여 실행할 수 있기를 원합니다.

OpenJDK 6, OpenJDK 7 및 Sun Java 6과 함께 Gnome 3 및 / 또는 Linux Mint 12 (64 비트)와 함께 Ubuntu 11.10을 실행하고 있습니다. 현재 기본값은 / usr / lib / jvm / java-6-openjdk / jre /입니다. 빈 / 자바

$ 여기서 javaws
javaws : / usr / bin / javaws

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

Java Web Start 응용 프로그램을 실행하려고 할 때 발생하는 오류는 다음과 같습니다.
