> It'd be nice to be able to write a base class for a @Component with an @Activate method taking the Map<String,Object> of configurations and performing field or setter injection of configurations via @Property - but the annotation is not retained at runtime right now due to CLASS not RUNTIME RetentionPolicy on @Property.
> Any idea why not? Was this on purpose or just an oversight?
> e.g. it'd be nice to be able to code components like this (and get the SCR and MetaType metadata auto-generated)
> {code}
> public abstract class MyAbstractComponent {
>     @Activate
>     public void activate(Map<String, ?> configuration) throws Exception {
>        // use introspection to find the fields and setters with @Property annotated...
>     }
> }
> ...
> @Component(name = "foo")
> public FooComponent extends MyAbstractComponent {
> @Property
> private int foo;
> @Property
> private String bar;
> ....
> {code}
