One thing I've learned is java 8 should give us some performance boost due to
improvements in CAS contention improvements. We use these types extensively on
the hot path

Yes but isn't that the JVM doing that? Compiling with 8 shouldn't effect that.
I'm not a big fan of going to 8 at the moment, to me, just because i'm not sure
the added value outweighs the pain you add to users.
