For example a strong use case for these events is data validation:

Makes sense. This won't work for async listeners, nor allowing the listener direct
access to javax.transaction.Transaction object. Perhpas an Event.abortTransaction() would
do the trick.
BTW I still don't like the need to invoke "isPre()". IMO you should
provide a way to register the Listener to happen only after or before;
the isPre method can stay where it is for convenience but it bothers
me that you have to call it on each invocation, it should be optional,
for example for those cases in which I need two different operations
to happen before/after and I'm too lazy to code two different
listener.
+1. Making it an attribute to the @Listener annotation would do just that.
