[8u-dev] Request for Approval: 8134150: Make Timing both threadsafe and efficient

[Attila Szegedi]

Please approve.

Bug: https://bugs.openjdk.java.net/browse/JDK-8134150
jdk9 webrev: http://cr.openjdk.java.net/~attila/8134150/webrev.jdk9
jdk9 review thread: http://mail.openjdk.java.net/pipermail/nashorn-dev/2015-August/005044.html

Changes apply cleanly to jdk8u-dev after path reshuffling from modular source code layout, BUT I had to modify the source as Nashorn in JDK 8 must use -source 1.7, therefore I had to remove the use of a Function lambda: http://cr.openjdk.java.net/~attila/8134150/webrev.jdk8u-dev

Thanks,
  Attila.
