[Marcus Lagergren]

Please approve.

Bug: https://bugs.openjdk.java.net/browse/JDK-8057703
jdk9 webrev: http://cr.openjdk.java.net/~lagergren/8057703/webrev
jdk9 review thread: http://mail.openjdk.java.net/pipermail/nashorn-dev/2014-September/003420.html

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

Thanks,
  Marcus.
