Using SystemService was successful. Now I get the service injection.
The next problem is problem resolving a type from a wrapped jar file
when activating the component:

My bundle imports the package org.neo4j.graphdb (without a version number):
Import-Package: org.apache.karaf.system.management;version="[4.1,5)",o
rg.neo4j.graphdb,org.neo4j.graphdb.event,org.neo4j.graphdb.factory,or

The wrapped jar exports the package org.neo4j.graphdb but have no users
of that package:

Do I need to statically reference something in the org.neo4j.graphdb
package, to get things to work?
