What's the issue w/ fire async and mutable payload? Non-deterministic
behavior depending on thread?

Hi guys,
Always working on Async event concept and discussion around mutable
payloads. I was looking where in the spec we specified the fact that fired
payload are mutable. I red-read chapter 10 (
http://docs.jboss.org/cdi/spec/1.2/cdi-spec.html#events) twice and didn’t
found. I also browsed JIRA and TCK to find any ref to this feature and
found nothing. On the other hand it is not specified that payload should be
immutable ;)
I’d be happy if some of you could have a look and see if I missed
something.
If I’m not wrong, the mutable payload we (including myself) advertise in
CDI is a non portable feature (I’m the firs surprised here). So I propose
that :
1) We decide to write something in the specification about allowing or
forbidding it (I know some people not happy with this mix between observer
and visitor pattern)
1bis) Should we decide to forbid it by default, we should provide an
alternative mode to allow people using this unspecified feature
2) Forbid it for fireAsync()
Thanks for your feedback and your correction if I missed the feature in
the spec.
Antoine
