Hi all,
This is a reimplementation of collections created by the JEP 269 convenience
factory methods. These implementations are overall quite a bit smaller than
their conventional collections counterparts, particularly at small sizes. Lookup
performance for the hash-based structures (Set and Map) is not particularly
fast, though in most cases it's comparable to TreeSet/TreeMap. Further
improvements are likely possible.
There are no API changes in this changeset.
