* <p>The {@code @Nullable} annotations on the {@code equalityGroup} parameter imply that the

   * objects come from factory methods that are themselves {@code @Nullable}. In reality neither the
   * array nor its contents can be null, but it is not useful to force the use of {@code
   * requireNonNull} or the like just to assert that.
