I mean that to be able to use Aries Application on Karaf we must use

"deprecated APIs based on early drafts of OSGi RFC138
(org.osgi.service.framework.CompositeBundle,

org.osgi.service.framework.CompositeBundleFactory) in order to create
and manage these framework instances. My understanding is that Equinox
implements these APIs, but that the Felix does not"

which is not implemented by Apache Felix framework.
