I created an reproducer application (find attached "spring-soap.zip")  that acts as client and server, and this publishes the following operations:

• http://localhost:8080/async -> it uses a soap client to call concurrently using an async operation (this fails with the exception previously described)
• http://localhost:8080/sync -> it uses a soap client to call concurrently using an ordinary operation (ends without errors)
