> {code}
>     Threads.sleep(baseSleepBeforeRetries * sleepMultiplier);
> {code}
> Both baseSleepBeforeRetries and sleepMultiplier are integers. Without proper casting,
their product may be negative.
> Here is an example:
> {code}
>   static int i = Integer.MAX_VALUE-1;
>   static long j = i * 2;
> {code}
> value of j above is -4 while 4294967292 was the expected value.
