(also includes 8184690: add Collectors for collecting into unmodifiable List,
Set, and Map)
Hi all,
Please review the following changeset with specification changes to support the
following:
* new List.copyOf(), Set.copyOf(), and Map.copyOf() "copy factory" methods
* new Collectors.toUnmodifiableList, Set, and Map methods
* specification revisions to provide clearer definitions of "view" collections,
"unmodifiable" collections, and "unmodifiable views"
The specification text has walked back most uses of "immutable", changing many
occurrences to "unmodifiable". (People thought that putting a mutable object
into an immutable collection would somehow magically make the whole thing
immutable. Also, there was continual confusion with "immutable persistent" data
structures.)
This review is mainly about specification. Minimal implementations are included,
but no tests. Those will come later.
