JMS Transactions in Mule 2 - jms

Question

I tried setting this up for my project and it appears to work in the sense that a request is placed back on the queue if I kill Tomcat before it finishes. But if I let it run I get an exception.
The only thing I changed was adding the JMS transaction line below to a service that otherwise works fine. Is there a bug in Mule 2 or is there something else I need to do?
<service name="ChangeService">
<inbound>
<jms:inbound-endpoint
connector-ref="jmsConnectorWMQ"
address="${change.service.inbound.endpoint}?method=applyListToRecords"
transformer-refs="Jms2Obj TraceRouteInbound"
responseTransformer-refs="DiagnosticsXForm TraceRouteOutbound MessagePropertiesTransformer Obj2Jms">
<jms:transaction action="ALWAYS_BEGIN"/>
</jms:inbound-endpoint>
</inbound>
<component>
<interceptor-stack ref="InterceptorStack"/>
<spring-object bean="service"/>
</component>
</service>
The exception:
ERROR [asyncDelivery4][2012-10-18 13:52:21,123] - org.oclc.mule.interceptors.FaultHandlingInterceptor Invocation failed:
org.mule.api.service.ServiceException: Component that caused exception is: SedaService{ChangeServiceAnyXml}. Message payload is of type: JMSTextMessage
