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

Unfortunately I just realized that the mentioned workaround doesn't work :(

I'm investigating why it isn't I'm down to the following right now: 

answer = endpoints.get(getEndpointKey(uri));

in DefaultCamelContext does give me the wrong Endpoint, at least it's bound to the wrong URI. 

it's called from 

endpoint = resolveEndpoint(exchange, recipient);

in RecipientListProcessor.createProcessorExchangePairs(...)

The following scenario doesn't work right now for the workaround, this might be a different bug though: 
- Recipient A is resolved the way it should work and can be called
- if Recipient B is questioned it also works and can be used. 
- if Recipient A is questioned from the cache again, Recipient B is provided and therefore the requests end up 
  on the wrong host. 

I also added a comment to the mailing-list about this.

but maybe this is also because it seems to be a singleton, maybe setting it to non-singleton 
does work :)

> This is probably due to producers being cached based on unresolved endpoint URI, rather than the resolved endpoint URI. Haven't tested this theory out though.
