The handler is being invoked, I am printing the message before and after the
handling (inside the handler execution body), so I positive that the SOAP
message was changed.
Here is the trace :
Caused by: javax.xml.bind.UnmarshalException: Unable to create an instance
of com.mailvision.ws.blah.Criterion
