There's a small compatibility risk with this change, e.g., `List.copyOf(...).contains(null)` will throw NPE while `Collections.unmodifiableList(...).contains(null)` won't. If we accept that compatibility risk (which should probably be decided by CSR) it might also make sense to use `List.of()` for the empty case, which will reduce the number of List implementation classes returned from the API. ------------- PR: https://git.openjdk.java.net/jdk/pull/7356
