Attached are the Eclipse projects to duplicate this issue, one for the web services and one for the client test app. If you run these you'll see output similar to below....

Note the error condition above in red....service 1 is invoked when the client called service 2. If you run it long enough you can see the case of service 2 being invoked for service as well, as shown below:
