Thanks for the data, the numbers look fine.
Best regards,
Vladimir Ivanov
PS: as I told you privately, some Octane benchmarks are noisy and 5
forks aren't enough to get stable results.

Dear all,
please review and sponsor this change.
RFE: https://bugs.openjdk.java.net/browse/JDK-8062543
Webrev: http://cr.openjdk.java.net/~mhaupt/8062543/webrev.00/
The change removes the no longer needed MethodHandleImpl.castReference method.
Its uses are replaced with Class.cast.
Look good. I agree with Vladimir on checking for performance regressions (i
suspect/hope! there will not be any).
Paul.
Tested with:
* jtreg (java.lang.invoke, java.util.stream)
* JPRT (hotspot and jdk_lang test sets)
* UTE (vm.quick-pcl.testlist, vm.defmeth.testlist)
Thanks,
Michael
