Thomas Watson commented on ARIES-1328:
--------------------------------------

What meta-data in the using bundle declares that it needs the service?  
Subsystems does not do bytecode inspection.  The Aries implementation only 
knows how to process service capability/requirements based of blueprint 
meta-data or the Require/Provide-Capability headers using the osgi.service 
namespace.

> Application subsystem does not import services

>             Project: Aries
>          Issue Type: Bug
>          Components: Subsystem
>    Affects Versions: subsystem-core-1.2.0
>            Reporter: David Bosschaert
>         Attachments: api-bundle-1.0.0-SNAPSHOT.jar,

> I have an application Subsystem that has a bundle that looks for a service 
> via a service tracker.
> This service and its API is provided by pre-existing bundles (api-bundle, 
> svc-bundle2) in the parent subsystem. 
> The OSGi enterprise R5 spec states in 134.16.1 (Application Subsystems):
> "Any required capabilities that are not satisfied by the application's 
> constituents are automatically shared in (imported) from the parent 
> Subsystem."
> However when I install and start the application subsystem 
> (application-subsystem-nosvc), it does not find the services provided in the 
> parent.
> I'm attaching the bundles and subsystem to reproduce. The full source code 
> can be found here: https://github.com/coderthoughts/subsystem-examples
