WebLogic: Registered more than one instance with the same objectName

We keps getting an error in the logs:

BEA-149500> (RuntimeMBeanDelegate.java:255)
        at weblogic.management.runtime.RuntimeMBeanDelegate.(RuntimeMBeanDelegate.java:215)
        at weblogic.management.runtime.RuntimeMBeanDelegate.(RuntimeMBeanDelegate.java:193)
        at weblogic.management.runtime.RuntimeMBeanDelegate.(RuntimeMBeanDelegate.java:182)



until we restarted and it went away. No change was done in the configuration recently.

Looking in Oracle Support I found:

BEA-149500 Error Registered more than one instance with the same objectName using JDBC TLOG Store (Doc ID 1544879.1)

WebLogic Server tries to create a new MBean every time a PersistentStoreRuntimeMBean is called. This issue has been fixed in unpublished defect 16063328

Our MBean type is "JMSPooledConnectionRuntime" and not "PersistentStoreRuntime", but maybe the origin is the same... anyway I am not going to apply the patch, as this has occurred only once....
