I am running into the same problem trying to access an online learning site (http://www2.sunpoweruniversity.com/SunPowerContent/VAR/site/index.html). When I go to that page, it fails to finish loading and prints the following error messages to the console:

I can close the tab, but shortly afterwards the CPU usage for the Java process goes to 100%. I can manually kill the Java process and Firefox will still continue running. I am running Ubuntu 10.04 x86-64, and I have the following Java packages installed: icedtea6-plugin 6b18-1.8-0ubuntu1 openjdk-6-jre 6b18-1.8-0ubuntu1 openjdk-6-jre-headless 6b18-1.8-0ubuntu1 openjdk-6-jre-lib 6b18-1.8-0ubuntu1 sun-java6-bin 6.20dlj-1ubuntu3 sun-java6-fonts 6.20dlj-1ubuntu3 sun-java6-jdk 6.20dlj-1ubuntu3 sun-java6-jre 6.20dlj-1ubuntu3 I also tried installing sun-java6-plugin instead of icedtea and openjdk, but I still could not access the site. With Sun's Java plugin, I do not get any errors on the console and Firefox completely locks up. -- IcedTea Plugin Dont work APPLET https://bugs.launchpad.net/bugs/440841 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
