Description

When starting up Apache Sling with a MultiplexingNodeStore backend Sling's discovery mechanism fails to read the repository descriptors.

I noticed that these descriptors are registered as OSGi services for the other stores - Segment ( 'old' and tar ), Document.

The MultiplexingNodeStoreService should register these as well.
