@todo Different FailoverSupport implementation are needed on the same method call, in different situations. Forexample, when failing-over and reestablishing the bindings, the bind cannot be interrupted by a second fail-over, if it fails with an exception, the fail-over process should also fail. When binding outside of the fail-over process, the retry handler could be used to automatically retry the operation once the connection has been reestablished. All fail-over protected operations should be placed in private methods, with FailoverSupport passed in by the caller to provide the correct support for the calling context. Sometimes the fail-over process sets a nowait flag and uses an async method call instead. @todo Two new objects created on every failover supported method call. Consider more efficient ways of doing this,after looking at worse bottlenecks first.
