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:
OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-0ubuntu1)
OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode)

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.
