Everything solved! - My client bundle was not supposed to import org.apache.felix.bundlerepository, even though I needed the jar in the classpath. That solved the inconsistency problems. - I had to get the RepositoryAdmin service like it's shown in the tutorials (using RepositoryAdmin.class.getName()). I had no more problems using this because my inconsistency problems were solved.
