After installing a new package, osgi bundle is not getting reflected under bundles. When we checked in osgi-installer (<ip>:<port>/system/console/osgi-installer), it is showing mapping with old version's bundle here.
We uninstalled and deleted all versions of the the project package from package manager. Now Project is not present in /apps as but when we checked the mapping in osgi-installer and it was still there.
Installing package after increasing version is installing the bundle.
Manual installation of bundle through Felix console is working fine.
Issue #1 : Bundle with new version was not getting installed:
The issue was related to an older version of "org.apache.sling.installer.factory.configuration". I installed the newer version of this bundle from <host>:<port>/system/console using the "Install/Update" option at the top right and restarted the instance.
Old version was 1.2.1 and now i have installed 1.3.4.
Issue #2: Old bundle was present and if we were deleting it, it was getting reflected after server restart
We checked the bundle in crx-quickstart/launchpad/felix and it was pointing to non existing jar file. So we have deleted this bundle after taking the backup of AEM.
After server restart, bundle was gone from the server.
Extract your package.zip like how you extract normal zip file and check your bundle version inside the package under jcr_root/apps/<project>-packages/application/install/xxxx.jar and see if it is latest or not.
