> It is unexpected because 1 of the 2 chains points to the actual bundle that exports the package and the other of the 2 chains points to the base subsystem already installed in the runtime. In fact the bundle is part of that subsystem so it should consider both as exactly the same and not consider it as 2 chains he cannot resolve.
> Not sure if it is related to ARIES-1588 and the commit mentioned there but that commit does affect how already installed subsystems are taken into account in the resolve process.
> Note: we are using the felix resolver 1.4.0
