Ah I spotted it now. When Camel performs a redelivery its at *the
point of original* so it happens in the intercepted route. So what
happens is that it will just retry invoking that process method on
Processor because it threw the exception. It does not start all over
again, which means that the logic in the choice / when is not executed
on redelivery.
You will have to put that logic *inside* the Processor because that
being invoked again on redelivery attempts.
