Comment 9 for bug 728798

With Namoroka (today's nightly), I get:

Java Plug-in 1.6.0_24
Using JRE version 1.6.0_24-b07 Java HotSpot(TM) Client VM
----------------------------------------------------
exception: Permission denied: null.
java.lang.SecurityException: Permission denied: null

 at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
 at java.lang.Thread.run(Unknown Source)

Could this give any hints to the underlying problem?
I can also reproduce comment #1 with the same error.

Note that I'm using JRE 1.6.0_24.
