------------------------------------
Fix Version/s: Installer Core 3.5.2
> NPE on startup in ChangeStateTask.getSortKey
> --------------------------------------------
>
> Key: SLING-3522
> URL: https://issues.apache.org/jira/browse/SLING-3522
> Project: Sling
> Issue Type: Bug
> Components: Installer
> Affects Versions: Installer Core 3.5.0
> Reporter: Philipp Marx
> Assignee: Carsten Ziegeler
> Fix For: Installer Core 3.5.2
>
>
> ChangeStateTask.getSortKey will internally call getResource().getEntityId(),
> whereas getResource() might return null.
> I tracked this down on my system to be a concurrency issue where the
> ResourceState of the task is being updated from UNINSTALL to INSTALLED by an
> update event. Since the state is now INSTALLED getResource() will return null
> since it is checking for resource in state UNINSTALL oder INSTALL.
