InputStreamProvider not closing stream in writeTo

The InputStreamProvider class successfully copies data from the InputStream to the response OutputStream, but it doesn't close the InputStream. Unless I am missing something (always possible!) there is no way for the InputStream to be closed.

My use case is returning artifact content in an S-RAMP repository Atom API binding. In the Atom API binding, most endpoints return Atom formatted data. There is a /media endpoint for S-RAMP artifacts that will return the original raw binary content, which gets returned from the repository as an InputStream. My jaxrs method looks like this:

@GET
@Path("

{uuid}

/media")
@Produces(MediaType.TEXT_XML)
public InputStream getContent(@PathParam("uuid") String uuid)

{ return srampRepository.getArtifactContent(uuid); }

My expectation is that resteasy would close my InputStream when it was done streaming the content.
