code: public static final RetryPolicy retryUpToMaximumTimeWithFixedSleep(long maxTime, long sleepTime, TimeUnit timeUnit) {
      return new RetryUpToMaximumTimeWithFixedSleep(maxTime, sleepTime, timeUnit);
    }
docs: <p>
  Keep trying for a maximum time, waiting a fixed time between attempts,
  and then fail by re-throwing the exception.
