> When the InetSocketAddress object happens to be unresolvable (e.g. due to transient DNS
issue), the rpc proxy object will not be usable since the client will throw UnknownHostException
when a Connection object is created. If FailoverOnNetworkExceptionRetry is used as in the
standard HA failover proxy, the call will be retried, but this will never recover.  Instead,
the validity of address must be checked on pxoy creation and throw if it is invalid.
