Julian Reschke commented on OAK-14:
-----------------------------------
> MVCC wrt. observation: Semantics change somewhat since a session might
> receive events "from the future". That is, events from a newer revision than
> the current session's. Trying to get a node from an NODE_ADDED event might
> thus result in an ItemNotFoundException unless the session is refreshed. In
> contrast nodes referred to by a NODE_REMOVED events will still be visible to
> the session. An approach to mitigate this is to have read only sessions which
> are always on the newest revision (i.e. see all saved changes).
Maybe surface the revisionid in the event, so that "smart" event listeners have
more context?
