Description

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.

This is based on feedback provided by Todd in this comment.
