Jörg Hoh commented on SLING-8706:
---------------------------------

[~jmanuelbr] Using Java Optionals would be just another way to express the 
fact, that a certain field might not be present. You still can change the 
overall strategy or annotate any field individually with {{@Optional}}, the 
current behavior and the way annotations are working must not change.

> Injections for java.util.Optional<> should be automatic optional

> The current approach to support optional injections requires to annotate the 
> field with {{@Optional}} plus proper handling within the javacode (null 
> checks etc), which can be forgotten.
> So instead of
> {code}
> @Inject @Optional
> String fieldname;
> {code}
> it should also be possible to use this
> {code}
> @Inject
> Optional<String> fieldname;
> {code}
> with the very same semantic. But the developer is forced to deal with the 
> case that the value is not present.
