-----------------------------------------
Another small problem: 3.4.x support Java 1.6 and later. However the code fails
to compile with 1.6 - 5 warnings and 1 error (this is the core code, I didn't
get to the tests):

> ZOOKEEPER-938 addresses mutual authentication between clients and servers.
> This bug, on the other hand, is for authentication among quorum peers.
> Hopefully much of the work done on SASL integration with Zookeeper for
> ZOOKEEPER-938 can be used as a foundation for this enhancement.
