Thank you Raymond and BJ. Your suggestions were very appreciated. I was not aware of the Service Loader Mediator and for my use case, it seems the easier path. In fact, I think Ceki Gulcu had to switch to Service Loader while "JPMSing" SLF4J. The slf4j-osgi code is very interesting and uses some advanced stuff that will need to look with more attention.
Once again, thank you.
