Given what we know now vs when the collections library ws created, I think it would be a mistake to allow nulls. Developers that desperately want null in there have other mechanisms to achieve that, not just Optional. I too would argue against Optional in collections, at least until value types exist, but thats a social discussion, not one that can be controlled.

Nicely put.

It seems there's some consensus to disallow nulls. Whew! One bikeshed down, 23,498 to go. :-)
