Got it. Thanks for your kindly discussion and suggestion.

I notice the return value of the method `markWord::set_displaced_mark_helper` is `void`, but the method `markWord::displaced_mark_helper` has a not empty return value. It is the point I missed so that I submitted this wrong PR.

It is my negligence. Apologize for wasting your time.
