Java Control Panel doesn't want to save JRE changes?

Question

I'm trying to add some runtime parameters to the Java Plug-In so that I can debug an applet in my browser. I go to the Java ControlPanel, click the Java tab, and click "View..." and add the runtime parameters. After I click OK and close everything, it doesn't work. So I go back to the Java Control Panel, and the changes I just made are gone!

Has anyone else seen this? What's going on? Is this broken?
