Description

When using the failover load balancer, it works directly on the given exchange, and in case of a failover, it clears the exception state etc.

However this does not work too well as if you use a processor directly then you can mutate the message before failover, which mean when the exchange is failed over, then its a 100% copy of the input message, but the previously mutated message.

We should do like the other EIPs by doing a defensive copy of the exchange.
