In this case the WireFormatJMSTextReferenceInterceptor is being added to the wire twice for some reason and that's causing the problem. Don't know why yet but can you raise a JIRA [1] for the problem and I'll look at making a fix for it. Thanks Simon [1] https://issues.apache.org/jira/browse/TUSCANY
