Robert Munteanu commented on SLING-7811:
----------------------------------------
Does it make sense to instruct the OSGi installer to install the configurations
first and then start the bundles? This way we would ensure configurations are
always present when services are started and we could get rid of the
start/stop/configure/start cycle.
> NPE when repository is starting up

> 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
> Assignee: Robert Munteanu
> Priority: Major
> Fix For: JCR Base 3.0.6, JCR Oak Server 1.2.2
>
>
> 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.
