They seem unrelated and while I tend to think approval of this one is ok, the depending one isn't necessarily unless you can explain what it actually fixes and why this is an issue now. Thanks!

However, the patch of JDK-8353698 could not be applied cleanly because IPv6BoundHost.java added in JDK-8332020 does not exist in 21u. Therefore, since I confirmed that the bug of JDK-8332020 can be reproduced in 21u, I considered this PR as a PR that #1981 depends on.

OK thanks. Next time please explain in the PRs what the goal is. In this case, you want to backport JDK-8353698 to OpenJDK 21u and this is a dependency which seems low risk enough to bring it in as well. My original concern for JDK-8353698 was that JEP 400, which is in JDK 21 as well so it's OK.
