Prior to this change, ScheduledAnnotationBeanPostProcessor found any @Scheduled methods against the ultimate targetClass for a given bean and then attempted to invoke that method against the bean instance. In cases where the bean instance was in fact a JDK proxy, this attempt would fail because the proxy is not an instance of the target class. Now SABPP still attempts to find @Scheduled methods against the target class, but subsequently checks to see if the bean is a JDK proxy, and if so attempts to find the corresponding method on the proxy itself. If it cannot be found (e.g. the @Scheduled method was declared only at the concrete class level), an appropriate exception is thrown, explaining to the users their options: (a) use proxyTargetClass=true and go with subclass proxies which won't have this problem, or (b) pull the @Scheduled method up into an interface.
