Carsten Ziegeler commented on SLING-5828:
-----------------------------------------
>From that list the resourceresolver is looking for required components based
>on the SERVICE_PID - so in that case, we just need to check whether the value
>is a String or an array. If it is an array with more than one value, we can
>treat it as null
> Support multi-valued Constants.SERVICE_PID

> As shown by SLING-5827 it is possible for the Constants.SERVICE_PID property
> of an OSGi service to be an array or a Collection of String.
> Quoting [1], _The value of this property must be of type String, String[], or
> Collection of String_.
> We have several places in our code that assume the value to be just a String,
> I'll attach an initial list and confirm on our dev list that we need to fix
> them.
