----------------------------------

             Summary: EntityResourceList cleaning up resource instead of updating
                 Key: SLING-7466
                 URL: https://issues.apache.org/jira/browse/SLING-7466
             Project: Sling
          Issue Type: Bug
          Components: Installer
    Affects Versions: Installer Core 3.8.10
            Reporter: Dominik Süß
             Fix For: Installer Core 3.8.12


In case of a replaced launchpad containing an unchanged resource the EntityResourceList is
called for "addOrUpdate" of this Resource - in case the resource already exists but the digest
differs the method currently drops the new resource without updating the existing one keeping
the old dataUri.

The issue manifests if these RegisteredResources are currently in INSTALL state and the INSTALLED
version gets dropped subsequently.

This isn't just a theoretical case but was observed for cases where a bundle in an n-1 version
was patched to the same version provided in version n of launchpad and launchpad hasn't changed
for n+1. If the jcr version is then removed the installation of the outdated registeredResource
fails because of a wrong dataUri.
