Hi

You are right, it is a new code which was added to avoid some 
synchronization issues in case of the async client invocations.

FYI, the existing CXF RS oneway tests still work with this code but only 
because the client does set a oneway CXF exchange status before the 
invocation, in case of the proxy it is done if a CXF @OneWay method 
annotation is available, in case of WebClient if a 'OnewayRequest' HTTP 
header is set.

I'm going to fix it shortly:
https://issues.apache.org/jira/browse/CXF-7113

Cheers, Sergey
