Camel CXFRS - no message body reader for Response

Tue, 30 Apr 2019 06:39:31 -0700 

Hello,

we are facing an issue with Camel CXF-RS component after migrating from
version 2.17.6 to 2.20.1.

Use case:
Simple Proxy service with CXFRS server and client. Service class uses
Response object. Simple binding style is used. Target endpoint produces XML
response of Content-Type application/xml.

Expected:
XML response from the backend.

Result:
Exception No message body reader has been found for class
javax.ws.rs.core.Response, ContentType: application/xml... (expection below)

endpoints:
 <cxfcamel:rsServer id="restProxyEndpoint"
  address="${server.endpoint.rest}"
    serviceClass="RestServiceImpl">
      </cxfcamel:rsServer>

      <cxfcamel:rsClient id="restClientEndpoint"
      address="${client.endpoint.rest}"
      serviceClass="RestServiceImpl">
      </cxfcamel:rsClient>

Camel route:
<route id="AtomService-route">
<from
uri="cxfrs:bean:restProxyEndpoint?synchronous=true&amp;bindingStyle=SimpleConsumer&amp;propagateContexts=true&amp;continuationTimeout=120000"
/>
  <to
uri="cxfrs:bean:restClientEndpoint?propagateContexts=true&amp;throwExceptionOnFailure=false"
/>
</route>

Service class RestServiceImpl: (as suggested in camel docs
https://camel.apache.org/cxfrs.html)
@Produces(value="application/xml")
@Consumes(value="application/xml")
@Path("/")
public class AtomRestServiceImpl {
@POST
@Path("/{path: .*}")
public Response proxyRequestPOST(String request) {
return null;
}
}

Exception:
