    Description

      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());

      public class First {
        
         void observeMessage(@Observes @Priority(2000) Message message){} 
      }
      
      public class Second {
        
         void observeMessage(@ObservesAsync @Priority(2100) Message message){} 
      }
      
      public class Third {
        
         void observeMessage(@Observes @Priority(2200) Message message){} 
      }
      
      public class Fourth {
        
         void observeMessage(@ObservesAsync @Priority(2300) Message message){} 
      }
      

      What will be the order in this case? First, Third, Second, Fourth?
