A ServiceEvent listener. When a ServiceEvent is
fired, it is synchronously delivered to a BundleListener.
ServiceListener is a listener interface that may be
implemented by a bundle developer.
A ServiceListener object is registered with the Framework
using the BundleContext.addServiceListener method.
ServiceListener objects are called with a
ServiceEvent object when a service is registered, modified, or
is in the process of unregistering.
ServiceEvent object delivery to ServiceListener
objects is filtered by the filter specified when the listener was registered.
If the Java Runtime Environment supports permissions, then additional
filtering is done. ServiceEvent objects are only delivered to
the listener if the bundle which defines the listener object's class has the
appropriate ServicePermission to get the service using at
least one of the named classes the service was registered under.
ServiceEvent object delivery to ServiceListener
objects is further filtered according to package sources as defined in
ServiceReference.isAssignableTo(Bundle, String).
