LGTM.  I'm running Oracle testing now.
I'm not sure how to handle JDK-8357017 now in JBS.  Close it as a duplicate of the backout?  According to https://openjdk.org/guide, it sounds like it might have been more correct to use JDK-8357017 for the backout, and make it a subtask of JDK-8258229.
@TobiHartmann @JesperIRL , what do you think?
