HATEOAS com Jersey/JayWay

Programação Arquitetura
#1

Tenho o código…

@Path("usuario")
public class UsuarioResource extends HateoasApplication  {

	private Repository repo = new Repository();
	
	
	@POST
	@Path("login")
	public Response login(@FormParam("mail") String mail, @FormParam("pwd") String pwd){
		Usuario usuario = new Usuario(null,mail,pwd);
		if(usuario.doLogin(usuario, repo)){

			return Response.ok().build();
		}
			
		else
			return Response.ok().status(Status.FORBIDDEN).build();
	}
	
	@GET
	@Produces(MediaType.APPLICATION_XML)
	public Response list(){
		List<Usuario> usuarios  = new ArrayList<Usuario>();
		usuarios.addAll(repo.getSession().createCriteria(Usuario.class).list());
		GenericEntity<List<Usuario>> genericEntity = new GenericEntity<List<Usuario>>(usuarios){};
		return Response.ok().entity(genericEntity).type(MediaType.APPLICATION_XML).build();
	}
	
	
	@Linkable(value="listById")
	@GET
	@Path("{id}")
	@Produces(MediaType.APPLICATION_XML)
	public Response listById(@PathParam(value="id") String id){
		Usuario user = (Usuario) repo.getSession().get(Usuario.class,new Long(id));
		return HateoasResponse.created("listById",user.getIdUsuario()).entity(user).build();
	}

E a configuração no web.xml

Quando eu faço uma chamada via rest para o método listById, ocorre a exceção abaixo

Pelo que eu vi existe um Map usado para manter as anotações @Linkable mas a minha está null.

Agradeço a quem puder me ajudar
