`List.of()` can't be used here, since the elements are nullable, according to 
the documentation. But the the returned list can still be modified, by changing 
the given `elements` array. The input array must be explicitly copied:

public static <E> List<E> toList(E... elements) {
        return Collections.unmodifiableList(new 
ArrayList<>(Arrays.asList(elements)));
}
