Major Description
For OAK-805 and related issues we need a mechanism for making Jackrabbit DataStores instances available to NodeStore implementations so that they can look up references to binaries stored in such datastores.
In an OSGi environment the best approach is probably to have DataStores as OSGi services that the NodeStore can look up dynamically through the Whiteboard mechanism. In plain old Java we can just pass a DataStore reference to a NodeStore during initialization.
