 * We need to implement this method as a {@link TypeSerializerConfigSnapshot.SelfResolvingTypeSerializer}

 * as its snapshot.
 *
 * <p>When the {@link CollectionSerializerConfigSnapshot} is restored, it is incapable of redirecting
 * the compatibility check to {@link ArrayListSerializerSnapshot}, so we do it here.
