Description

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().
