Review Comment:
   Shouldn't we update the comment on the interface to be clear that a null 
param results a noop?
   
   I checked the implementation again for SetStatistics.setStatistics() and 
apparently there is no special handling for null inputs. I became a bit 
hesitant now because there giving a null stat file as param would result in an 
NPE when calling the Optional.of(statisticsFile).
   Not sure now if noop is the way to go here or the Precondition was better. 
Sorry to this back and forth. What do you think?
