>                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1790
>             Project: ZooKeeper
>          Issue Type: Bug
>          Components: server
>    Affects Versions: 3.4.6, 3.5.0
>            Reporter: Alexander Shraer
>            Assignee: Alexander Shraer
>             Fix For: 3.4.6, 3.5.0
>
>
> QuorumCnxManager.receiveConnection assumes that a negative sid means that this is a 3.5.0 server, which has a different communication protocol. This doesn't account for the fact that ObserverId = -1 is a special id that may be used by observers and is also negative. 
> This requires a fix to trunk and a separate fix to 3.4 branch, where this function is different (see ZOOKEEPER-1633)
