    Description

      See http://www.slideshare.net/MonicaBeckwith/garbage-first-garbage-collector-g1-7486gc-migration-to-expectations-and-advanced-tuning and https://twitter.com/rbranson/status/482113561431265281

      May want to default 2.1 to G1.

      2.1 is a different animal from 2.0 after moving most of memtables off heap. Suspect this will help G1 even more than CMS. (NB this is off by default but needs to be part of the test.)
