             Summary: ZooKeeper client NPE when updating server list on 
disconnected client
                 Key: ZOOKEEPER-1683
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1683
             Project: ZooKeeper
          Issue Type: Bug
            Reporter: Shevek


2013-04-04 22:16:15,872 ERROR [pool-4-thread-1] 
com.netflix.curator.ConnectionState.getZooKeeper (ConnectionState.java:84) -

The duff code is this:

ClientCnxnSocket clientCnxnSocket = cnxn.sendThread.getClientCnxnSocket();
InetSocketAddress currentHost = (InetSocketAddress) 
clientCnxnSocket.getRemoteSocketAddress();
boolean reconfigMode = hostProvider.updateServerList(serverAddresses, 
currentHost);

Now, currentHost might be null, if we're not yet connected. But 
StaticHostProvider.updateServerList indirects on it unconditionally.

This would be caught by findbugs.
