  * A basic, no operation {@link ResponseErrorHandler} implementation suitable

+ * for ignoring any error using the {@link RestTemplate}.
+ * <p>This implementation is not suitable with the {@link RestClient} as it uses
+ * a list of candidates where the first matching is invoked. If you want to

+ * registering a noop {@link ResponseSpec.ErrorHandler ErrorHandler} with a
+ * predicate that matches all status code, see
+ * {@link RestClient.Builder#defaultStatusHandler(Predicate, ErrorHandler)}.
