code: public final Cache2kBuilder<K, V> maxRetryInterval(long v, TimeUnit u) {
      config().setMaxRetryInterval(u.toMillis(v));
      return this;
    }
docs: If a loader exception happens, this is the maximum time interval after a
  retry attempt is made. For retries an exponential backoff algorithm is used.
  It starts with the retry time and then increases the time to the maximum
  according to an exponential pattern.
