According the this code:

  static bool layout_helper_is_objArray(jint lh) {
    // _lh_array_tag_obj_value == (lh >> _lh_array_tag_shift);
    return (jint)lh < (jint)(_lh_array_tag_type_value << _lh_array_tag_shift);
  }

comment, the implementation should use _lh_array_tag_obj_value, not _lh_array_tag_type_value

Is the comment or code wrong?
