ReferenceArrayList::elements returns K[] #163

Closed nnym closed 4 years ago

nnym commented 4 years ago

Attempting to assign the array turned by ReferenceArrayList::elements to K[]—or anything else other than Object[]—causes a ClassCastException because Object[] cannot be cast to anything except Object[], so either elements should return Object[] instead or the element array should actually be a K[].

Please read the class documentation.
