native-image: Problem with Scheduled annotation

[mhalbritter]

When running the native-image from the spring-native sample scheduling-tasks on the sb-3.0.x branch, i get the following exception:

@sdeleuze is the registrar really necessary? Unless the implementation has changed, adding @Reflective should register the annotation as well.

Now the agent is available it would be nice to have a test for this.

[sdeleuze]

I will double check.

[sdeleuze]

It does not work without the registrar (maybe something to refine on @Reflective to refine later), I will add related tests.
