Thanks.  This has been pushed to jdk/jdk: https://hg.openjdk.java.net/jdk/jdk/rev/b9529fcbbd33

Sure.  These are on my radar.

1. For 8, I have prepared a backport webrev: http://cr.openjdk.java.net/~fyang/8248219-8u-backport/webrev.00/ 
     Jtreg tested with an 8u aarch64 release build.  OK for aarch64-port/jdk8u-shenandoah?

2. For 11, patch applies cleanly to jdk11u-dev and I have added a jdk11u-fix-request label and corresponding comment on the issue.

3. For 15, should I simply add 15 to " Affects Version/s" of the issue and push to jdk/jdk15 after necessary test?
     Please confirm if this is correct in procedure.
