Didn't someone(tm) work on an asynchronous event module?
Were you at the JUDCon in Boston? :) I was asking about something that was already in EJB 3.1 ...
I am working on a quartz module for my own application server, but that is different, I think. I believe I would have to override that DeferredEventNotification and the code that creates a new instance of that is all, but I don't know how to override that since it is built into the framework (Weld).
