RFR: 8166365: Small immutable collections should provide optimized implementations when possible

[Attila Szegedi]

Collections.java:

4987         @Override
4988         public int hashCode() {
4989             return (k == null ? 0 : k.hashCode()) ^
4990                    (v == null ? 0 : v.hashCode());

Why not use Objects.hashCode here too, that is return Objects.hashCode(k) ^ Objects.hashCode(v) ?

Attila.
