Hello XWiki experts,
in the deployment of our staging environment, we met a strange thing: many exceptions such
as:
Failed to send event
[org.xwiki.bridge.event.DocumentCreatedEvent@72dd82d1] to listener
[com.xpn.xwiki.plugin.activitystream.impl.ActivityStreamImpl@55b8b91f]

What's surprising is that the activitystream jar (3.5.1) is there and its hibernate
mapping and that no complaint is made about the lack of such.
Also bizarre is that the same webapp (differences in xwiki.cfg and web.xml only) on our
development server does not have this issue.
Is there something I've done wrong?
Thanks in advance
Paul
