RestResponse usability

[geoand]

Description

I expected to be able to write something like:

    @Path("{id}")
    @GET
    public RestResponse<String> something(int id) {
        if (id % 2 == 0) {
            return RestResponse.ok("good");
        } else {
            return RestResponse.notFound();
        }
    }

However I can't because notFound() returns RestResponse<Void>.

This really limits the usability of RestResponse

Implementation ideas

No response

Yeah, I noticed this too. I'm not sure how to solve it, but we should.

I am not sure either, but this is severely limiting the usability of RestResponse
