Hi,
Please approve the backport of 8177449 to 8u-dev.
Bug: https://bugs.openjdk.java.net/browse/JDK-8177449
JDK9 Changeset: http://hg.openjdk.java.net/jdk9/dev/jdk/rev/d584006ddd5d
JDK9 Review Thread: http://mail.openjdk.java.net/pipermail/i18n-dev/2017-March/002280.html

Changes apply cleanly to jdk8u-dev after path reshuffling.
