Resteasy does not set Expires attribute for JAX-RS NewCookie correctly in EAP 7

Issue

Resteasy does not set Expires attribute correctly when testing the following JAX-RS application using javax.ws.rs.core.NewCookie to set Expires attribute to current date:

    @GET
    @Path("get0")
    public Response get0() {
        System.out.println("MyEndpoint get0 - Version 0 Cookie");
        NewCookie cookie = new NewCookie("Name", "Value", "/", "*", 0, "comment", 3600, new Date(),
                true, true);
        return Response.ok().cookie(cookie).entity(cookie.toString()).build();
    }  

    @GET
    @Path("get1")
    public Response get1() {
        System.out.println("MyEndpoint get1 - Version 1 Cookie");
        NewCookie cookie = new NewCookie("Name", "Value", "/", "*", 1, "comment", 3600, new Date(),
                true, true);
        return Response.ok().cookie(cookie).entity(cookie.toString()).build();
    }  

V0 Cookie set Expires attribute but it's not same to a specified time (current date). It looks calculated from Max-Age attribute:

$ curl -v localhost:8080/myapp/rest/get0
> GET /myapp/rs/get0 HTTP/1.1
> ...
>
< HTTP/1.1 200 OK
< ...
< Set-Cookie: Name=Value; path=/; domain=*; secure; HttpOnly; Max-Age=3600; Expires=Mon, 22-Aug-2016 01:12:52 GMT
< ...
< Date: Mon, 22 Aug 2016 00:12:52 GMT
<

V1 Cookie does not set Expires attribute:

$ curl -v localhost:8080/myapp/rest/get1
> GET /myapp/rs/get1 HTTP/1.1
> ...
>
< HTTP/1.1 200 OK
< ...
< Set-Cookie: Name=Value; Version=1; Path=/; Domain=*; Secure; HttpOnly; Max-Age=3600
< ...
