after fix:

> Key: NXP-5995
> URL: https://jira.nuxeo.org/browse/NXP-5995
> Project: Nuxeo Enterprise Platform
> Issue Type: Improvement
> Affects Versions: 5.4
> Reporter: Benoit Delbosc
> Assignee: Benoit Delbosc
> Fix For: 5.4.1
>
>
> Async listener should not iterate on events when receiving EventBunde
> public void handleEvent(EventBundle events) {
> for (Event event : events) {
> handleEvent(event);
> }
> }
> For async listener events are ReconnectedEventBundle and iterating on them
> will reconnect all events, this means opening a session and create document
> model and context for each event (see
> ReconnectedEventBundleImpl.getReconnectedEvents())
> This is very expensive and useless if the listener is not interested in any
> event in the bundle.
> A first optimisation may be to use containsEventName in the listener to check
> if the interesting event is present in the bundle,
> that should not reconnect any events.
