Please review the webrev at
This webrev refactor java.util.Collector interface to allow an
intermediate type used for accumulation and then produce final result
type with a 'finished' function.
Collectors are updated to reflect the changes, and quite a few API changes,
toStringJoiner -> joining
Return type becoming Optional<T> when appropriate
sumBy -> a set of summing[Int,Long,Double]
I'll put specdiff up later for those interested in API changes.
