JsonpRequestBuilder - Timeout while calling

Trying to retrieve an object in my GWT client using JsonpRequestBuilder from a cross domain server.  The call goes to server and server does respond with the correct value but the client keeps throwing "Timeout while calling http://localhost:8080/layouts/AVhARgXQW9-o1U_GgvJa" message. Here are the code snippets.

The call is made from this class -

public class EntityFisher {
    public String fish(String id) {
        JsonpRequestBuilder builder = new JsonpRequestBuilder();
        String url = "http://localhost:8080/layouts/" + id;
        AsyncCallback<LayoutJson> callback = new LayoutFisherCallback();
        JsonpRequest<LayoutJson> layoutJson = builder.requestObject(url, callback);
  ...
        return t;
    }
}

LayoutJson.java

public class LayoutJson extends JavaScriptObject {
    protected LayoutJson() {}
    public static final native LayoutJson build(String json) /*-{
        return eval('(' + json + ')');
    }-*/;

    public final native JsonArray<PointJson> getCoordinates() /*-{
        return this.coordinates;
    }-*/;
}

LayoutFisherCallback.java

public class LayoutFisherCallback implements AsyncCallback<LayoutJson> {
    @Override
    public void onFailure(Throwable caught) {UiFlag.flag(caught);}

    @Override
    public void onSuccess(LayoutJson layoutJson) {
        JsonArray<PointJson> pointsJson = layoutJson.getCoordinates(); // code never reaches this point
        UiFlag.flagNull("pointsJson", pointsJson);
        ArrayList<Point> coordinates = new ArrayList<>();
        UiFlag.flag(coordinates.toString());
    }
}

the call is kicked off like this

   EntityFisher fisher = new EntityFisher();
   fisher.fish(id);

I see everything done correctly on the server side and the JSON

{"coordinates":[{"x":100,"y":90,"z":0,"index":0,"time":1478546404606},{"x":118,"y":121,"z":0,"index":1,"time":1478547002023},{"x":154,"y":121,"z":0,"index":2,"time":1478547079871}]}

is sent back as expected but I keep getting the "Timeout while calling http://localhost:8080/layouts/AVhARgXQW9-o1U_GgvJa" on the client side. When I make the request through GWT RequestBuilder (as a same origin request) everything works good.

Any idea what's wrong in the above code?

I would appreciate any help.

Thanks
