With jvm 1.8.0_40 (OSX) subprocess invocation fails with
"CICompilerCount of 1 is invalid; must be at least 2", so upping
to 2, and lo and behold, the unit tests work.

I think that a better solution that will give more consistent results is to disable TieredCompilation. So, leave the CICompilerCount line as is and add this straight after.

  // disable tiered compilation otherwise setting CICompilerCount=1 is invalid
  "-XX:-TieredCompilation",
