FULL PRODUCT VERSION :
java version "1.6.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-beta-b59g)
Java HotSpot(TM) Client VM (build 1.6.0-beta-b59g, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
Signed applet jars seem to be getting ignored.

No permission grant dialog appears and permissions are not granted.

This is occuring with signed applets that work fine in Java 1.3.1, 1.4.2, and 1.5.0 Plug-Ins.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run signed applet.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Permission grant dialog appears and permissions are granted.
ACTUAL -
No permission grant dialog appears and permissions are not granted.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Err: unable to load plugin privilege set, using default.
java.security.AccessControlException: access denied (java.lang.RuntimePermission getProtectionDomain)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.lang.Class.getProtectionDomain(Unknown Source)
at wt.security.ClassQuery12.run(PrivilegeSet.java:464)
at java.security.AccessController.doPrivileged(Native Method)
...

The wt.security.ClassQuery12 class is ours, but this issue should not be occuring inside a signed applet inside a privileged action.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
Our signed applets are rather complex, but this should be repeatable with any.
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
I assume that disabling security would work, but that's not a solution.
