To add events ordering feature we have two choices:
1) Use @Priority from common annotation specification (JSR-250) (vote +1)
pros:
- more consistent with other ordering mechanism we already have in CDI (Interceptors, decorators, Alternatives)
- more Java EE consistent
cons:
- time consumed in JSR 250 MR participation (@Priority must be update to support parameter for target)
- as @Priority is not part of Java SE, CDI light on java SE will have to add the jsr250 jar as dependency only to have this annotation (which will make it a little less light)
2) Add a parameter to @Observes annotation to give order to an observer (vote -1)
pros:
- works out of the box (we can add this property without ask for other specs modification)
- avoid two annotations to declare an ordered observer (simpler usage)
cons:
- less Java EE spirit
- could be seen as an inconsistency with the way we order Interceptors, Decorators and Alternatives.
