> I think this needs to be specified. E.g. what happens if I fire async event and have more matching sync and async observers? Are all sync observes called first in given order with no regard to async observers priority?
> For example:
> {{event.fireAsync(new Message());}}
> {code}
> public class First {
>
> void observeMessage(@Observes @Priority(2000) Message message){}
> }
> {code}
> {code}
> public class Second {
>
> void observeMessage(@ObservesAsync @Priority(2100) Message message){}
> }
> {code}
> {code}
> public class Third {
>
> void observeMessage(@Observes @Priority(2200) Message message){}
> }
> {code}
> {code}
> public class Fourth {
>
> void observeMessage(@ObservesAsync @Priority(2300) Message message){}
> }
> {code}
> What will be the order in this case? First, Third, Second, Fourth?
