> Components: JCR
> Reporter: Michael Dürig
>
> JcrResourceListener.onEvent(EventIterator) keeps references to all Event
> instances in the passed iterator. This has turned out as a memory bottleneck
> e.g. in the scenario where a large sub-tree is copied and NODE_ADDED events
> for all nodes in that sub-tree are generated.
> Furthermore Oak will be able to handle arbitrarily large transactions
> (Session.save). In such cases the EventIterator might contains millions of
> events.
