Review Comment:
   As said in the other comment, I proposed this change as `tryAcquire` already 
threw exceptions and `OutputFormat` is not user facing so I felt we could 
change to a more generic exception throwing. But it is true that even if it is 
not a user braking change, it is a source-compatibility breaking change. So if 
you prefer I'll make `tryAcquire` throw an unchecked exception in both Sink and 
OutputFormat so that we don't need to change the throw clause.
