------------------------------------

@Hadrian

I think it requires a bit more work than its possible to do over a weekend.
 
I would like to propose that this work should not hold up 2.0m2 release. I 
would really like that to get out as its a major leap over 2.0m1. We have done 
tons of work since and if it was a 1.x series it it would have constituted a 
new x.+1 release alone.

After the m2 I would love to give us the time needed to research and work with 
the API to find the right solution.

> The code in DefaultEndpoint.createExchange(Exchange exchange), calls on 
> getExchangeType() to figure out if a new copy of Exchange needs be created.  
> The code relies though on the generic argument of the Endpoint type to figure 
> out the actual Exchange type.  With the generics removed part of CAMEL-872, 
> getExchangeType() always returns null, forcing a copy every time.
> There is no real need to extend Exchange, so the proposal for this to make 
> the Exchange final and move the component specific bits, if any,  in the 
> Message.
