    ZOOKEEPER-2762: Multithreaded correctness Warnings

    This patch adds the dependency required to suppress findbugs warnings.
    The warning we are trying to suppress in three locations is:
    VO_VOLATILE_INCREMENT: An increment to a volatile field isn't atomic
    This code increments a volatile field. Increments of volatile fields aren't atomic. If
more than one thread is incrementing the field at the same time, increments could be lost.
    The places where we increment a volatile field are either deprecated (which I do not think
we should fix), occur in a synchronized block, or are only ever executed by a single thread.
    In addition, this patch also fixes AT_OPERATION_SEQUENCE_ON_CONCURRENT_ABSTRACTION: Sequence
of calls to concurrent abstraction may not be atomic in QuorumCnxManager.java.

You can merge this pull request into a Git repository by running:
