> NPE when repository is starting up due to repository manager shutdown

>
> Key: SLING-7811
> URL: https://issues.apache.org/jira/browse/SLING-7811
> Project: Sling
> Issue Type: Bug
> Components: JCR
> Affects Versions: JCR Oak Server 1.1.4, JCR Base 3.0.4
> Reporter: Carsten Ziegeler
> Priority: Major
> Fix For: JCR Oak Server 1.2.6
>
>
> With the latest Sling Starter, the following NPE occurs in the logs. It seems
> to be harmless, nevertheless we should fix it:
> For now I assigned it to both, JCR Base and Oak Server, as it's unclear which
> one it is. Interestingly we've released Oak Server 1.2.0 but are not using it
> in the starter.
