> JAX-WS: Client engine should detach input stream after use
> ----------------------------------------------------------
>
> Key: AXIS2-3966
> URL: https://issues.apache.org/jira/browse/AXIS2-3966
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: jaxws
> Reporter: Rich Scheuerle
> Assignee: Rich Scheuerle
> Original Estimate: 0.5h
> Remaining Estimate: 0.5h
>
> Background:
> The JAX-WS client engine (dispatch/proxy/asyncResponse) is ultimately responsible for creating business objects (or exception) for the client call.
> After that point, the unmarshalling is complete and the input stream (from the transport layer) is no longer needed.
> Problem:
> In some situations, the input stream is not closed. Since the input stream comes from the transport layer, this could result in resources not being freed. (For example connection resources may not be freed).
> Solution:
> The soap builder code already wraps the incoming input stream with an axiom DetachableInputStream. The DetachableInputStream has a detach method, which copies the remainder of the original stream to a local stream. This allows the original stream (i.e. the HttpInputStream) to free its resources without any loss of information for the consumer of the stream.
> I am making changes to the jaxws dispatch/proxy/asyncResponse code to always call DetachableInputStream.detach() after all of the business objects are unmarshalled. This will effectively guarantee that the input stream from the transport layer is closed and allow resources to be freed.
> I have am testing these changes and will integrate soon. All of the changes are in the jaxws module
