I have the following Mule configuration that I'm running with Mule 2.0.1

<cxf:endpoint name="ClientIn"
address="http://localhost:10080/Client" synchronous="true"
frontend="simple">
</cxf:endpoint>

<vm:endpoint name="ClientHandler"
address="vm://clienthandler.queue" />

When I test this by invoking the webservice at the "ClientIn" endpoint I get
this exception:

This seems to be happening as result of using the wire-tap-router with the
cxf endpoint. The same configuration when used with an Axis end point works
OK.
