[jira] [Commented] (SLING-5014) Installer blacklist, to avoid reinstalling older bundles

["Henry Kuijpers (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-5014?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15949268#comment-15949268 ] 

Henry Kuijpers commented on SLING-5014:
---------------------------------------

Is it also possible to make exceptions to this installer blacklist? I.e. the sling_bootstrap.txt says that certain bundles must be uninstalled (upgraded AEM), but we are still installing these bundles and requiring them (feature not yet upgraded after upgrade).

> 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.
