Hi, @buddyliao, we can have a look.

First of all, I see that you have included JDK-8253763 in this commit, which seems to make sense. Can you please add the issue to this PR via the "/issue add" command?

Furthermore, JDK-8251570 seems to be a follow up. Do you plan to backport this as well? If so, you could use a "dependent PR" to also propose a backport for this and we can test it together. Please let me know and I can guide you on how to do it.
