Major Description
After the first time the service is started and the service is invoked in parallel with multiple threads I get the following
stacktrace and the service returns a soap-fault:

If I invoke a fresh started service once with a single thread and after that with multiple threads it works fine.
The attached patch fixes that but I'm not sure if it's the right place and who is at fault here. The overhead by this patch should be minimal.
