> ComponentContext.getService() did not return the expected service when invoked. It works with a @Reference field is defined for the service in the Impl class but it failed without the annotation. The reference is defined in the SCDL.
> Section 1.4.1.1 of the specification says, "When a component implementation needs access to a service where the reference to the service is not known at compile time, the reference can be located using the component's ComponentContext." So, this should work without @Reference defined.
