ERROR DESCRIPTION:
When using the eXtreme Scale OpenJPA L2 cache implementation, a thread was being created without the correct AccessController.doPrivileged() call. When the OpenJPA L2 is first referenced, the following message and exception is seen in the SystemOut.log:

SECJ0314W: Current Java 2 Security policy reported a potential
violation of Java 2 Security Permission.
Refer to the InfoCenter for further information.
Permission:
modifyThreadGroup : Access denied
(java.lang.RuntimePermission modifyThreadGroup)

com.ibm.ws.objectgrid.container.
ObjectGridContainerImpl$PlacementServiceUpdater in

LOCAL FIX:

PROBLEM SUMMARY

USERS AFFECTED:
All users of WebSphere eXtreme Scale Version 7.0.0.0 FIX2 or above who are using the eXtreme Scale OpenJPA L2 cache.

PROBLEM DESCRIPTION:
java.security.AccessControlException: Access denied

is thrown.

RECOMMENDATION:

The WebSphere eXtreme Scale runtime was changed to add the necessary AccessController.doPrivileged() method call when creating the thread.

PROBLEM CONCLUSION:
An interim fix will be made available for this APAR. A future cumulative fix will correct the problem for WebSphere eXtreme Scale Version 6.1.0.5.
