----------------------------------

             Summary: Can not get real exception when getChildren more than 4M
                 Key: ZOOKEEPER-4313
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4313
             Project: ZooKeeper
          Issue Type: Bug
          Components: java client
    Affects Versions: 3.4.6
            Reporter: Li Jian


When use zkClient or curator listener one zookeeper node more than 4M will cause endless loop，because they catch error code for KeeperException.Code.ConnectionLoss then will retry getChildren method after a monent。
The root reason for zookeeper invoke readLength method occor IOException for “Package len is out of range” but when deal with the following process zookeeper changed the real exception to ConnectionLoss。
