the icedtea plugin and other firefox addons have side effects. install
the xmarks addon (configuration isn't necessary), start the sun java
test applet: cpu load goes to 100%, closing the page doesn't terminate
the process. deinstalling the addon and rechecking doesn't show the 100%
load.

I cannot reproduce this issue. I have xmarks installed and the applets
mentioned on https://launchpad.net/bugs/551328 work fine for me...

I too cannot reproduce this. The links on
https://launchpad.net/bugs/551328 works for me and gives no issues
before and after installing xmarks addon. (However firefox refuses to
startup with xmarks installed)

Is this still an issue for you?

What version of IcedTea did you use for the latest test?

I installed the xmarks addon and tried
http://www.javatester.org/version.html, the applet loads fine and the
CPU usage is nominal.

Maybe my bug is entirely different as I don't have xmarks addon.
Loading an applet also crashed Mozilla Minefield earlier today, see http://crash-stats.mozilla.com/report/index/64e22535-6944-4f95-9c79-1015f2101029

I tried it with a 64-bit VM as well. Are you comfortable trying this
with the latest version of the plugin?
