Impossible de construire une instance de `Java.time.ZonedDateTime` (aucun créateur, comme la construction par défaut, n'existe)

J'apprends Jackson sous JAX-RS 1.0. Le serveur renvoie une réponse HTTP comme suit:

{
  "url": "http://localhost:8080/api/123",
  "created": "2018-05-26T09:21:26.301+02:00"
}

et je dois désérialiser la réponse JSON en un Java appelé ProductCreated:

public class ProductCreated {

  @JsonProperty("created")
  private final ZonedDateTime created;

  @JsonProperty("url")
  private final String url;

  public ProductCreated(String url) {
    this.url = url;
    this.created = ZonedDateTime.now();
  }

  @JsonCreator
  public ProductCreated(
      @JsonProperty("url") String url,
      @JsonProperty("created") ZonedDateTime created) {
    this.url = url;
    this.created = created;
  }

  public String getUrl() {
    return url;
  }

  public ZonedDateTime getCreated() {
    return created;
  }
}

Dans mon test, il n'a pas réussi à construire l'objet ProductCreated:

Product p = new Product("123", "foo");
ProductCreated c = wr.type(MediaType.APPLICATION_JSON)
                     .accept(MediaType.APPLICATION_JSON)
                     .post(ProductCreated.class, p);

Et l'erreur côté client est:

Impossible de construire une instance de Java.time.ZonedDateTime (aucun créateur, comme la construction par défaut, n'existe): pas de méthode constructeur/fabrique d'argument de chaîne à désérialiser de la valeur de chaîne ('2018-05-26T09: 21: 26.301 + 02: 00')

Côté serveur, j'ai configuré le mappeur JSON (mais aucun effet sur mon test car le test est côté client?):

private static JacksonJsonProvider newJacksonJsonProvider() {
  ObjectMapper mapper =
      new ObjectMapper()
          .registerModule(new ParameterNamesModule())
          .registerModule(new Jdk8Module())
          .registerModule(new JavaTimeModule()); // new module, NOT JSR310Module
  mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
  mapper.setDateFormat(new StdDateFormat());
  return new JacksonJsonProvider(mapper);
}

Qu'est-ce que j'oublie ici?

Comme l'a souligné @PaulSamsotha, je dois également enregistrer le JacksonJsonProvider côté client:

ClientConfig cc = new DefaultClientConfig();
cc.getSingletons().add(ShopApplication.newJacksonJsonProvider());
wr = Client.create(cc).resource(Main.BASE_URI.resolve("products"));

qui contient la solution personnalisée:

private static JacksonJsonProvider newJacksonJsonProvider() {
  ObjectMapper mapper =
      new ObjectMapper()
          .registerModule(new ParameterNamesModule())
          .registerModule(new Jdk8Module())
          .registerModule(new JavaTimeModule()); // new module, NOT JSR310Module
  mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
  mapper.setDateFormat(new StdDateFormat());
  return new JacksonJsonProvider(mapper);
}
