James Taylor commented on PHOENIX-1143:
---------------------------------------
If we just make the methods in PhoenixDriver synchronized instead of double
locking, does the issue go a way, as that's our external entry point? I don't
think we'd see any performance impact in this change, and I'd rather keep
things simple.
> Prevent race condition between creating phoenix connection and closing
> phoenix driver/connection query services.
