> Currently every implementation of a {{FailoverProxyProvider}} will need to perform its own synchronization to ensure that multiple concurrent failed calls to a single client proxy object don't result in multiple client fail over events. It would be better to put this logic in {{RetryInvocationHandler.invoke}}.
