Description

With creation of response without content, based on javax.ws.rs.core.Response.ResponseBuilder. I get wrong Content-Type.

Sample of REST resource (This is not valid rest service, but I want only show strange behaviour)

package com.sozix.rest.service;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@Path("/hello")
public class HelloResource {
	// 1
	@GET
	// 2
	@Produces(MediaType.APPLICATION_JSON)
	public Response greeting() {
		// 3
		return Response.noContent().build();
	}
}

At 1) No matter which kind of request (GET, POST, PUT, DELETE) i will invoke. Issiue is the same.
At 2) I set that method produces ONLY Content-type: application/json
At 3) Constructing response without content, using javax.ws.rs.core.Response.ResponseBuilder

Invoking servcie

$ curl --header "Accept: application/json" http://localhost:8080/hello -v
I'm setting header that as client accept only JSON content type.

$ curl --header "Accept: application/json" http://localhost:8080/hello -v
* About to connect() to localhost port 8080 (#0)
*   Trying 127.0.0.1... connected
* Connected to localhost (127.0.0.1) port 8080 (#0)

But as you can see at response i'm getting Content-Type: text/xml. Which is not i'm expecting.
