Hi Nicolas, Carbon-Mediation version is 4.6.19 used in EI 6.1.1. You can use dynamic imports to your osgi bundle as well. Are you creating an osgi bundle or just jar only? If you are creating a jar then you need to copy it into lib folder. otherwise, you can copy your OSGi bundle into dropins folder.
