difference in javadoc vs annotation references
I have an abstract class with a service reference in it and a getter
method for retreiving it. If I use the javadoc method of declaring the
reference, classes that extend the abstract are able to call the getter
and use the service. Switching to the annotation method of declaring the
reference results in the getter returning null. Is this expected
behavior? Is there a way to make it work using the annotations?

I'd like to thank Carsten for helping me off list, and share the answer
in case someone is looking for it in the future. The abstract class
needs to be annotated with '@Component(componentAbstract=true)'.

That would really be a retention.
Stuart, could you please send me a simple example demonstration this?

I think you have to put the annotation on the *class* of the concrete class, since the annotation process does not look at parent classes. (possibly a retention issue).
There was a similar problem but different problem with QDocs.
