> 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 not being able to connect to the first brokers from
> the broker list but at the end it manages to connect to the one of the
> following brokers from the broker list
> * there is a racing condition between waking up the connection state waiter
> and closing the phisical connection on receiving ConnectionClose command from
> the broker. 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 instead -1 is returned by read operation, 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.
