Description

The ResolutionCache is currently listening on event admin events for changes in adapter factories. However, support for event admin is only optional for the adapter manager implementation which makes this approach less reliable.
On the other hand since many years, Adaption services are registers which provides a reliable mechanism. We should use service events instead.
