> Jsonp support via Jsonp(In,PreStream,PostStream)Interceptor (as described in http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-JSONWithPadding%28JSONP%29) conflicts with GZIPOutInterceptor.
> With a very simple test application request "http://localhost:7543/12?_jsonp=abc" without Gzip results in the following response 
> bq. abc(24);
> With Gzip:
> bq. abc();24
> Apparent reason is that the method org.apache.cxf.jaxrs.provider.jsonp.AbstractJsonpOutInterceptor.writeValue(Message, String) writes directly to the response output stream. When the method is changed to write to {{message.getContent(OutputStream.class)}}, responses with and without Gzip interceptor become the same "abc(24);", as expected.

> Service code:

> import javax.ws.rs.*;
> @Path("/") @Produces("application/json")
> public class Service {
>     @GET @Path("{id}") public int find(@PathParam("id") int id) {
>         return id * 2;
>     }
> }
> {code}
> Configuration (with Gzip)
