Laird:
You are exactly right. My get() calls a Future<Integer> method decorated
with @Asynchronous which actually returns AsyncResult() from a SessionBean.
But, I am injecting the SessionBean with @Inject. l also tried changing
@Inject to @EJB just to beat a dead horse.
Anything else you think I might try?

btw -- thanks for the link on merge
