---------------------------------------------------------------
In looking at your patch it appears that log4j-api already expresses a
dependency on core.osgi? I find osgi so confusing as I have no idea how the
api can be dependent on the implementation of the api.

Yeah - that "possible" patch is never going to happen. log4j-api cannot depend
on log4j-core.
