--------------------------------
The three findbugs warnings are not introduced by this Jira. There are on-going
work to fix them in separate Jiras.
> RetryUpToMaximumTimeWithFixedSleep needs to behave more accurately

> RetryUpToMaximumTimeWithFixedSleep now inherits
> RetryUpToMaximumCountWithFixedSleep and just acts as a wrapper to decide
> maxRetries. The current implementation uses (maxTime / sleepTime) as the
> number of maxRetries. This is fine if the actual for each retry is
> significantly less than the sleep time, but it becomes less accurate if each
> retry takes comparable amount of time as the sleep time. The problem gets
> worse when there are underlying retries.
> We may want to use timers inside RetryUpToMaximumTimeWithFixedSleep to
> perform accurate timing.
