Please approve.

Bug: https://bugs.openjdk.java.net/browse/JDK-8137333
jdk9 webrev: http://cr.openjdk.java.net/~attila/8137333/webrev.jdk9
jdk9 review thread: http://mail.openjdk.java.net/pipermail/nashorn-dev/2015-September/005341.html

Changes apply cleanly to jdk8u-dev after path reshuffling from modular source code layout.

Thanks,
