[Hohensee, Paul]

Np. And of course we're on GitHub now and have moved to PRs!

Thanks,
Paul

Hi Paul,

It seems I missed to reply to you.
Thank you for the explanation!

Thanks,

    Hi, Serguei,

    For 8u, we're still using mailing lists, not PRs. We'll move to PRs when 8u moves to github, which I believe is scheduled for real soon now (for 8u332). Hedong (I think I got his first name right!) just needs to tag the JBS issue with jdk8u-fix-request and add a Fix Request comment pointing to your review email (at https://mail.openjdk.java.net/pipermail/jdk8u-dev/). hg-updater will create a backport JBS issue after the commit.

    Thanks,
    Paul

    Hi Hedongbo,

    The backport looks okay to me.
    But I do not see where I can mark it as approved.
    Do you have a PR (Pool Request) or a backport bug number?

    Thanks,
    Serguei

        Hi,

        Please review the backport of JDK-8173361 to 8u.
        Bug: https://bugs.openjdk.java.net/browse/JDK-8173361
        11u commit: https://hg.openjdk.java.net/jdk-updates/jdk11u/rev/99bdef096320
        8u webrev: https://cr.openjdk.java.net/~dongbohe/8173361/webrev.00/

        This patch doesn't apply cleanly.
        I turned NoSafepointVerifier to No_Safepoint_Verifier because JDK- 8146690[1] changed the naming convention.
        I removed the mutexLocker.cpp changeset because JDK-8047290[2]  does not exist in 8.
        I added the CLDClosure* to ServiceThread::oops_do because JDK- 8154580[3] does not exist in 8.

        Tested with tier1. No regression in tests.
        Follow-up fix JDK-8235218[4] is planned to be backported as well.
