      Description

      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.

      Found one Java-level deadlock:
