PROBLEM SUMMARY

USERS AFFECTED:
WebSphere Process Server v6.1 Users

PROBLEM DESCRIPTION:
System runs into NullPointerException
when sending response message for an
asynchronous interaction.

RECOMMENDATION:
None

When the invocation have a request expiration configured but
not a response expiration, The following error is encountered:
WMSG0031E: Exception processing JMS Message for MDB
_import.FaultImportEIS, JMSDestination
GenImportFault/FaultImport_RECEIVE_D :
java.lang.NullPointerException
at com.ibm.ws.sca.internal.async.sib.SIBAsyncHandler.
createSIBusResponse(SIBAsyncHandler.java:641)

The request message was picked up before it expires, thus
generating a legitimate response message. This response
message shall never expires. We are in the middle of returning
this response message to caller when the problem occurs.

PROBLEM CONCLUSION:                                             
Code fix to allow response expiration to be left un-configured.
