> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: felix-1.8.1
> Reporter: David Bosschaert
> Assignee: Richard S. Hall
> Priority: Minor
> Fix For: felix-2.0.0
>
>
> The OSGi specification says about the call to BundleContext.getService():
> "1 If the service has been unregistered, null is returned.
> 2 The context bundle's use count for this service is incremented by one.
> 3 If the context bundle's use count for the service is currently one and the
> service was registered with an object implementing the ServiceFactory
> interface, the ServiceFactory.getService(Bundle, ServiceRegistration)
> method is called to create a service object for the context bundle."
> The OSGi specification says about the call to ServiceFactory.ungetService():
> "The bundle's usage count for that service object must drop to zero
> after this call returns; that is, the bundle is about to release its last
> dependency on the service object."
> However, the current implementation decrements it just after ServiceFactory.getService() and just before ServiceFactory.ungetService().
