pas d'injection de source d'erreur lors de l'utilisation de plusieurs @PathParams le repos de Ressources à l'aide de Jersey

Je suis en train de travailler sur un simple service web Restful en Rest /Jersey avec Tomcat 7. Les choses fonctionnent bien si tous mes Chemins d'accès comprennent un seul paramètre. Si je comprend celui qui utilise plus d'un paramètre, je rencontre le "Pas d'injection de source" d'erreur lorsque je tente de frapper tout de la ressource chemins pris en charge par ma classe de ressource - même ceux qui avaient travaillé avant. Si j'en commentaire ce morceau de code, tous mes autres chemins de fonctionner comme prévu. Mais si je ne commentez ce morceau de code, je ne peux pas utiliser TOUT mes chemins.

Voici un extrait de mon code:

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

//get all the information about a specific item
@GET
@Path("/{id}")
@Produces(MediaType.APPLICATION_JSON)
public String getItem(@PathParam("id") String itemId)
{
    String answer = "{";
    answer += "\"itemid\":\"" + itemId + "\",";
    answer += "\"type\":0,";
    answer += "\"sector\":322948,";
    answer += "\"created\":53249098220";
    answer += "}";

    return answer;
}

//if I comment out this method, all is fine; 
//if I leave it in, error is thrown when I make any restful call
//query to see if there is a new item for user
@Path("/loc/{userid}/{xloc}/{yloc}")
@Produces(MediaType.APPLICATION_JSON)
public String getNewitem(@PathParam("userid") String userId,
    @PathParam("xloc") Number xLoc,
    @PathParam("yloc") Number yLoc)
{
    String answer = "{\"itemid\":\"abcdefgh\"}";
    return answer;
}

Ici est la trace de l'erreur:

Des suggestions pour contourner ce problème? Je suis à l'aide de jersey 2.12. Est-ce un bug connu?
