Should EventImpl.fireAsync use ExecutorServices from the ServiceRegistry
by Benjamin Confino
Hello
I have a customer with the following
@Inject
Event<Message> event;
@Resource
ManagedExecutorService threadPool;
public void fireAsyncEvent() {
System.out.println("Sending Async-Message via CDI");
event.fireAsync(new Message("Hello"));
}
public void fireAsyncEvent_2() {
event.fireAsync(new Message("Hello"),
NotificationOptions.ofExecutor(threadPool));
}
fireAsyncEvent() eventually results in an NPE when a JSF class attempts
tries to call CDI.current() fireAsyncEvent_2() works correctly. I was
hoping that it would be possible to fix fireAsyncEvent to remove the
dependency on passing in an executor service every time it is used.
We currently set an executor service into the weld service registry, and I
was wondering if org.jboss.weld.event.EventImpl fetch the executor
service from the service registry. Either only when fireAsync is called
without any NotificationOptions, or perhaps more aggressively and set the
default executor service if NotificationOptions are provided but do not
explicitly contain an executor service (The javadoc is unclear, but I
believe calling ofExecutor() provides this functionality).
Before going further with this I wanted to ask for a quick sanity check.
Is this fix plausible?
Regards
Benjamin
