[8u40] Request for Approval: 8060238: Reports for optimistic test run overwrite those for pessimistic run

[Attila Szegedi]

Please approve.

Bug: https://bugs.openjdk.java.net/browse/JDK-8060238
jdk9 webrev: http://cr.openjdk.java.net/~attila/8060238/webrev.00
jdk9 review thread: http://mail.openjdk.java.net/pipermail/nashorn-dev/2014-October/003644.html

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

Thanks,
  Attila.
