> By [~elserj] on PHOENIX-5070:
> This looks to me that the getAccessControllers() method is not correctly
> implementing the double-checked locking "approach" as per
> https://en.wikipedia.org/wiki/Double-checked_locking#Usage_in_Java (the
> accessControllers variable must be volatile).
> If we want to avoid taking an explicit lock, what about using AtomicReference
> instead? Can we spin out another Jira issue to fix that?
