Marcel Reutegger commented on OAK-7756:
---------------------------------------
Registering a {{NodeStore}} also as an {{Observable}} sounds reasonable to me,
but since the {{Observable}} provides read access to the {{NodeStore}}, I would
think the same application code that restricts access to the {{NodeStore}} will
also restrict access to an {{Observable}}.
So even if Oak exposed the {{NodeStore}} as an {{Observable}} you'd be back to
square one.
> Node stores are not registered as Observable

> Key: OAK-7756
> URL: https://issues.apache.org/jira/browse/OAK-7756
> Project: Jackrabbit Oak
> Issue Type: Bug
> Reporter: Oliver Lietz
> Priority: Major
>
> The recently released [Sling Clam
> module|https://github.com/apache/sling-org-apache-sling-clam] uses the
> NodeStore service for listening to add and change events.
> That works fine on Sling but a cast to {{Observable}} is required.
> On AEM it works not OOTB as
> {{com.day.crx.sling.server.impl.jmx.SecureContentRepositoryAccess}} prevents
> direct access to {{NodeStore}} and therefore
> {{SecureContentRepositoryAccess}} component has to be disabled to make it
> work.
> To get rid of the cast and the limitation on AEM node stores should be
> registered as {{Observable}} also.
> * {{SegmentNodeStore}} in {{SegmentNodeStoreService}}
> * {{DocumentNodeStore}} in {{DocumentNodeStoreService}}
> * {{CompositeNodeStore}} in {{CompositeNodeStoreService}}
