["Joshua McKenzie (JIRA)" <ji...@apache.org>]

Joshua McKenzie commented on CASSANDRA-7486:
--------------------------------------------

We also need to update conf/cassandra-env.ps1 and bin/cassandra.ps1 to keep Windows' configuration in parity with linux on this ticket; the linked branches appear to be linux env only.

> 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.)
