That comment simply says that you could previously add some kind of Advice (including retry) on a <poller/> but there was no way to advise a single component - that's what the new 2.2 feature is (the ability to add an advice to JUST an endpoint). In addition, we happened to supply some "standard" advices that we felt might be useful in such a situation (retry, circuit breaker, expression evaluatiing).
We had never provided any 'standard' Advice classes (besides the transaction interceptor) for use on a poller - it was (and still is) there to allow users to roll their own advice, and apply it to the entire flow.
If you would like to see a set of supplied advices for that context, open a New Feature JIRA (or even better - contribute them!)
