Hi, why you don't just put this as private package. You will avoid class loading issue this way.
In OSGi, not all is necessary an import. It could be a private package and/or embed dependency. It means the packages are embedded in the bundle. The bundle is "fat" but you avoid classloading issue this way, especially when the dependency is not designed for OSGi. Unfortunately, I wanted to create neo4j bundle at ServiceMix, but it's not possible due to neo4j license.
