> Failover functionality on 0-8/0-9.x java client does not restore the connection in the following scenarios:
> * when on initial establishing of the connectivity the connection object is marked as closed after to not being able to connect to the first brokers from the broker list but managed to connect to the one of the following brokers from the broker list
> * there are racing condition between waking up the connection state waiters and closing the phisical connection. As result, waiters are notified, new connection is created and closed afterwards.
> * on killing the broker when no IOException is thrown from socket input/output streams but -1 is returned by read operation instead, the failover starts but IoSender thread is left running. As result, on multiple reconnection attempts the thread resources can be exhausted and that can potentially result in OOME.
