Does jetty overwrite custom http status code ? - rest

Question

I am trying to develop a rest api for my service wherein I set custom http status code depending on authorisation failure. But when I test it out using curl I am receiving 404 instead of 403. I am perplexed as to what might be causing this? Please help.
This is what I see from curl output or swagger UI:
root#ubuntu:~# curl -X GET http://localhost:8082/mr/v1/topic/bhakk -v
Note: Unnecessary use of -X or --request, GET is already inferred.
* Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8082 (#0)
> GET /mr/v1/topic/bhakk HTTP/1.1
> Host: localhost:8082
> User-Agent: curl/7.47.0
> Accept: */*
>
< HTTP/1.1 404 Not Found
< Date: Mon, 07 May 2018 22:00:10 GMT
< Exception: serviceBlockedException

< Server: Jetty(9.2.z-SNAPSHOT)

* Connection #0 to host localhost left intact
{"error_code":40301,"message":"This service does not have access to the resource."}
Here is the code:
public Collection<String> list(#HeaderParam("x-nssvc-serviceid") String serviceID) {
Date now = new java.util.Date();
if (! ctx.getSecurityRestrictions().isServiceAllowed(uri, httpHeaders, "Describe", "Cluster", "kafka-cluster"))
throw Errors.serviceBlockedException(ctx,httpServletResponse);
List<String> topicsCopy = new ArrayList<String>(topics);
for (Iterator<String> iterator = topicsCopy.iterator(); iterator.hasNext();) {
String topic = iterator.next();
if (! ctx.getSecurityRestrictions().hasAccess (serviceId, "Describe", "Topic", topic)) {
iterator.remove();
}
}
return topicsCopy;
}
public static RestException serviceBlockedException(Context ctx,HttpServletResponse httpServletResponse) {
httpServletResponse.setHeader("Exception","serviceBlockedException");
httpServletResponse.setStatus(Status.FORBIDDEN.getStatusCode()); <----// here i am setting status code.
return new RestNotFoundException(SERVICE_ID_BLOCKED_MESSAGE, SERVICE_ID_BLOCKED_ERROR_CODE);
}

Kafka sets the Response 404 status in its RestNotFoundException
