Hi Martin, Thank you very much for the heads-up. I have filed a bug for the same: https://bugs.openjdk.java.net/browse/JDK-8190259
Thank you for the patch as well. This will be integrated into JDK along with the tzdata2017c. Regards, Ramanand.

One thing we noticed is that one of the java.time tck tests was broken by tzdata rewrite of history.
