> The only non-reference field in the CompositeNodeState is the path. Assuming we have many node states in the memory, it may be a bit expensive to store their paths in the memory.
> On the other hand, after the recent optimizations (see linked issues), the set of the nodes which should be wrapped with the CompositeNodeState is limited to:
> * /
> * /oak:index and its direct children
> * /jcr:system
> * /jcr:system/nt:permissionsStore
> That's why it makes sense to use a string cache to store all the paths.
