      Description

      The various fixed-arg factory methods mostly call internal varargs constructors, causing array creating and element copying. The resulting array is passed to a constructor that creates another array and copies it (or clones it) again. Consider the List.of(...) methods that call the ListN() constructor. This is quite wasteful.

      A likely solution is for the fixed-arg API methods to call an internal varargs method, which can trust the array because it originated internally.
