public class DelegateAsyncProcessor
A Delegate pattern which delegates processing to a nested AsyncProcessor
which can
be useful for implementation inheritance when writing an Policy

the service is being stopped. This method will also be invoked
if the service is still in uninitialized state (eg has not
been started). The method is always called to allow the service
to do custom logic when the service is being stopped, such as when

AsyncProcessor
Processor.process(org.apache.camel.Exchange)
, but the caller supports having the exchange asynchronously processed.
If there was a failure processing then the caused Exception
would be set on the Exchange

exchange
- the message exchangecallback
- the AsyncCallback
will be invoked when the processing of the exchange is completed.
If the exchange is completed synchronously, then the callback is also invoked synchronously.
The callback should therefore be careful of starting recursive loop.
