Hi, @snazarkin,
since JDK-8191278 has a few follow-up fixes, could you please use the recently enabled feature of dependent pull requests and add all those. We can then test them together.
To do that, create the backport of e.g. JDK-8226871 on top of this branch and then open a PR to branch pr/173 of this repository.
Please let me know if you have further questions.
Thanks!
