> NPE in sling EventListener on missing user id
> ---------------------------------------------
>
> Key: SLING-2773
> URL: https://issues.apache.org/jira/browse/SLING-2773
> Project: Sling
> Issue Type: Bug
> Components: JCR
> Reporter: Alex Parvulescu
>
> The Oak repository impl doesn't yet provide user id information on events which makes for a NPE on the sling side (See OAK-675).
> Providing null as user id is considered legal , so probably a null guard is in order [0].
