Carsten Ziegeler commented on SLING-5014:
-----------------------------------------

[~dsuess] Thanks for the patch, unfortunately , the patch also contains a lot of reformatting. In addition I think this should go directory into the core, avoiding the unstable dependency to the existence of another service. The installer might start before the blacklistener service etc. So I think making this a feature of the OSGi installer itself, is the better option.
Could you please provide an updated patch?

> In case a bundle has mutliple install candiates only the highest version (with the highest priorty for the same versions) wins. An uninstall directive in the Sling bootstrap.txt file or provisioning model uninstalls this version. The way the OSGi install behavior is defined this lets the next artifact in the priority queue to get active and consequently only leads to downgrade to the next in the queue.
> As the uninstall directive declares a range that should be uninstalled the expectation is that after a startup with such an uninstall directive none of the declared versions are in an installed state. In consequence the OSGi installer must save this metainformation in the state that prevents a downgrade to a version that is part of an active uninstall directive.
