Consider a case where a request is completed on the server side, the
runtime serializes the response entity and now finishes with

The resource itself is created per every request. In CXF it is possible
to configure the runtime to call indirectly via a resource factory a
pre-destroy method immediately after the invocation has returned but
also optionally after the entity has been written to the output stream.

I think Jersey did something similar long before we did it in CXF.
Marek, any comments about it ?

So what I'm wondering about, what we end up with a double close() call
if say a Response entity is InputStream, once - by Response impl, the
other one - by the per-request resource instance

May be it's not a problem, but raising it just in case
