Por ejemplo, digamos que quieres tener una *operación de path* que permita actualizar ítems y devolver códigos de estado HTTP 200 "OK" cuando sea exitosa.

Pero también quieres que acepte nuevos ítems. Cuando los ítems no existan anteriormente, serán creados y devolverá un código de estado HTTP 201 "Created".

Para conseguir esto importa `JSONResponse` y devuelve ahí directamente tu contenido, asignando el `status_code` que quieras:

    @Override
    protected ObjectiveProperties newObjectiveProperties(final String resourcePath, final PropertyFilter propertyFilter) {
        return new ObjectiveProperties(resourcePath) { // for e.g. checking existence and filtering value
            Cache<String, String> cache = CacheBuilder.newBuilder().build();

            @Override
            public String get(final String propertyKey) {
