Async can't be used in EndpointInterceptor

[scolem]

I have a web service, and want to log the SOAP request and response messages. I am attempting to do this in a EndpointInterceptor.

When using a custom logger, which logs messages asynchronously, all async call stop being asynchronous when added to the interceptor.

Here is a small project to demonstrate the issue: https://github.com/scolem/retailerInterface. By adding and removing the injected AsyncService in WSSoapMessageLogger, the tests will either pass or fail.
