[jira] [Updated] (CXF-7964) Ensure CXF JAXRS stack (client/server) can be used for roundtrips

["Romain Manni-Bucau (JIRA)" <ji...@apache.org>]

Romain Manni-Bucau updated CXF-7964:
------------------------------------
    Description: 
Today (3.3.0), if you use a Client to get a response and copy it to return in an endpoint (http proxy pattern) like that:

{code}
    private Response passthrough(final Response source) {
        final Response.ResponseBuilder builder = Response.status(source.getStatus());

        source.getStringHeaders().entrySet().stream()
              .forEach(e -> builder.header(e.getKey(), String.join(",", e.getValue())));

        final InputStream forwardedData = source.readEntity(InputStream.class);
        return builder.entity(forwardedData).build();
    }
{code}

A client calling that endpoint will freeze cause of the forwarded input stream.

Edit: the server endpoint returns a CompletionStage (tomcat 9.0.14 and cxf 3.3.0), I didn't take time yet to investigate if it is coming from the completion stage or not, I just know in some older 3.2 it was the stream which was not properly closed.
