jmh under Java 8

[Richard Warburton]

Hi,

In general jmh looks much preferrable to caliper, but, whilst compiling
works fine on a released Java 7 build, trying it on a Java 8 Lambdas build
(b86) fails with the following error:

[ERROR] Failed to execute goal

Which looks like you've got a dependency on the jrockit flight recorder
APIs.  I can't actually find these checked into the OpenJDK build.  Have I
made a mistake here, or are they simply not open source?  If they aren't
open source is it even possible me to use jmh to benchmark the java 8
lambdas build?
