Michael Han created ZOOKEEPER-2488:
--------------------------------------

             Summary: Unsynchronized access to shuttingDownLE in QuorumPeer
                 Key: ZOOKEEPER-2488
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2488
             Project: ZooKeeper
          Issue Type: Bug
          Components: server
    Affects Versions: 3.5.2
            Reporter: Michael Han
             Fix For: 3.5.3, 3.6.0


Access to shuttingDownLE in QuorumPeer is not synchronized here:

https://github.com/apache/zookeeper/blob/3c37184e83a3e68b73544cebccf9388eea26f523/src/java/main/org/apache/zookeeper/server/quorum/QuorumPeer.java#L1066
https://github.com/apache/zookeeper/blob/3c37184e83a3e68b73544cebccf9388eea26f523/src/java/main/org/

The access should be synchronized as the same variable might be accessed 
in QuormPeer::restartLeaderElection, which is synchronized.
