Error description

In WebSphere Application Server, using a SIB messaging engine
and file store (not a data store), SystemOut.log shows
CWSIS0002E followed by "CWSOM1015E: ObjectManager", and there
is a corresponding ffdc file which contains:

Exception = java.lang.NullPointerException
Source = com.ibm.ws.objectManager.ObjectManagerState:run
probeid = 1:3061:1.23.1.11
Stack Dump = java.lang.NullPointerException

Problem summary

****************************************************************
* USERS AFFECTED:  Users of the default messaging provider     *
*                  for IBM WebSphere Application Server        *
*                  Version 6.1 or Version 7.0                  *
****************************************************************
* PROBLEM DESCRIPTION: NullPointerException logged to an FFDC  *
*                      with probeid 1:3061:1.23.1.11           *
*                      when using the file store.              *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
An FFDC report as follows might be generated from a messaging
engine using a file store:
Exception = java.lang.NullPointerException
Source = com.ibm.ws.objectManager.ObjectManagerState:run
probeid = 1:3061:1.23.1.11

As a result of this exception, the messaging engine reports
itself as unhealthy to the application server's high
availability manager, causing the JVM to be terminated and
restarted on the next is-alive healthcheck.

The problem occurs because code within the file store
attempts to access a WeakReference without first checking if
the reference is null.

Problem conclusion

The fix for this APAR corrects the file store code to check
the weak reference is not null before accessing it.

The fix for this APAR is currently targeted for inclusion in
fix pack 6.1.0.31 and 7.0.0.9.  Please refer to the Recommended
Updates page for delivery information:
