>>> This is a review request for a small spec clarification to java.util.stream.Collectors, that appears to be a minor oversight in the original spec.
>>> Many of the Collectors that accumulate, group, etc, elements into a Collection, and do not accept a Collection supplier, come with a caveat on the Collection they create, along the lines of, "There are no guarantees on the type, mutability, serializability, or thread-safety of the ... returned".
>>> This caveat should be applied to all Collectors that create such Collections.
>> Thanks for doing this. The toMap docs are missing 'thread-safety", otherwise looks good.
> Fixed. Webrev and specdiff have been updated in place.
