If I fire an asynchronous event without any special notification options, my understanding is that the container will arrange for that event to be delivered to asynchronous observers.

Is (appropriate) asynchronous observer method invocation guaranteed to happen at some point?  Section 10.2.2 seems to hint that it is:

"Event fired [sic] with the fireAsync() method is [sic] fired asynchronously. All the resolved asynchronous observers (as defined in Observer resolution) are called in one or more different threads."

To me, this says that if I use fireAsync() to fire an event, then if I have a (resolved) asynchronous observer method for it it will be notified before the container closes no matter what.

(I believe I am observing a race condition somewhere in here that might show that Weld's default asynchronous event delivery machinery does not actually get around to delivering the event I've queued up before the container closes.  Sometimes the event is received, sometimes it is not.  Obviously if there is no such guarantee this could be permitted behavior.)

Best,
