The issue is for trellisldp to solve surely? The transitivity is an
indirect jena-osgi dependency and a direct jena dependency.
Or a PR to improve `jena-osgi` (which does not get much use or at least not
much user@ questions). You may also wish to take that up with CommonsRDF. I'm
not sure OSGi is helping here.
`jena-osgi` does not affect the oaj.atlas issue between `jena-arq` and
`jena-base`.
This PR is for the org.system split package. This seems completed. I'd like
to get this merged and other matters taken up in separate issues/JIRA so we can
make incremental progress.
