The p2 repository of oxygen-1a contains two version of org.eclipse.osgi. P2 mirrors both of them and thus a feature is created that the target editor of eclipse cannot use.
Solution: allow exclusion of the older version, since it is not actually required. We cannot set "lastestVersionOnly" for mirroring as this will remove more artifacts that we actually need (e.g. older antlr runtime and current version).
