Adam Morrison updated JBCACHE-1522:
-----------------------------------

    Description: 
I was using SimpleTest in local mode.

It creates several threads, all of which concurrently access the results' DescriptiveStatistics objects, but DescriptiveStatistics is not a thread safe object.

On multicore/SMP systems these races can corrupt the benchmarks results.
