Francesco Mari commented on OAK-2401:
-------------------------------------
bq. Further in a given system there should be one and only one BlobStore
configured and they should be configured once and not changed once a setup is
running.
This is, in my opinion, another reason to have a static reference instead of a
dynamic one. Having a static references makes a clearer statement about the
kind of dependency existing between a {{SegmentNodeStoreService}} and a
{{BlobStore}}.

> The SegmentNodeStoreService is prone to deadlocks because of the way in which
> is synchronizes access to the _SegmentNodeStore_ delegate.
> The issue can now be seen on #deactivate, when the deregistration is being
> synchronously broadcast and if a referring service calls #getNodeStore the
> deadlock happens.
