Cannot inject blueprint exposed service with annotations

[Dario Amiri]

Hello all, I'm hoping you can help me with an issue that is baffling me.

In one bundle I'm exposing a service through blueprint

     <service id="dataSvc"
         interface="org.example.data.Data"
         ref="data">
     </service>

In another bundle I'm trying to inject that service with annotations

     @Reference(unbind = "unsetData")
     public void setData(final Data data) {
         this.data = data;
     }

     @Reference
     public void unsetData(final Data data) {
         this.data = null;
     }

Unfortunately, this is not working. The reference always ends up being 
null. I have other services that I am injecting into the same class 
which are exposed by yet other bundles using annotations and declarative 
services which work fine. Also I can clearly see all the services if I 
run either the "ls" or "services" command in Karaf. Can anyone tell me 
if I am doing something wrong or help me troubleshoot this issue?

Regards,

D
