Any performance differences between these methods and `objArrayOopDesc::oop_iterate_elements_range` are attributable to differences in inlining behavior. For this reason, `ALWAYSINLINE` is applied. Further investigation is ongoing to improve inlining of calls through `objArrayOopDesc::oop_iterate_elements_range`.
