Why do you want to create a processor definition that way? The example only uses the processor to illustrate the point, it has access to the exchange and can easily remove it from the inflight repo of the camel context. To do it your way I don't know without an IDE handy, I avoid working with low level camel API in my apps, so maybe first try to avoid it in this case or help me understand why you need it.
Maybe you're only doing this to set a dynamic path for the consumer and producer?
