This bug was filed by the security PIT group, so I am reassigning to the AWT person who recently added the sun.awt.nativedebug code.

Similar error condition for DFLoadTest.

Caused by: java.security.AccessControlException: access denied (java.util.PropertyPermission sun.awt.nativedebug read)

There was a recent putback that is probably causing this error:

4638447: AWT Debugging Support Enhancements (Java level)

No codereviewer was listed in the SCCS comments, so I can't cc them.
