Proxy CXF : Spring DSL : Body empty when client side in timeout

In case of a CXF proxy in payload mode.
If a call to the client side fall in timeout, the server side of the proxy respond by a soap message with an empty body after 30s.

So, to describe the problem in depth:
Our project is composed by :

• One CXF endpoint expose a Webservice.
• One CXF endpoint invoke a Webservice.
• a route between that endpoints to dispatch messages.
• an http-conduit that set the Receivetimeout to 300000ms (300s).

So, there is no way to explain why the server side is responding after 30s.
