[Hannes Wallnöfer]

Please approve back port of 8176511 to 8u-dev.

Bug: https://bugs.openjdk.java.net/browse/JDK-8176511
Webrev: http://cr.openjdk.java.net/~hannesw/8176511/webrev/
Review thread: http://mail.openjdk.java.net/pipermail/nashorn-dev/2017-March/006893.html

Changes apply cleanly to jdk8u-dev after path reshuffling.
