CDI Events

[gboro54]

Are events thread safe? For example if I inject the Event object into a bean and have multiple threads firing that one injected event object is this safe? Would I be better wrapping my event firer in a Singleton and having a single point for all threads to fire the event object?

I don't see what could go wrong.

You fire an event in your current thread, and the observers use the same thread.

I mean, Weld / CDI doesn't do anything special about it -- you can call that non-thread safe if you like.

e.g. if your observers are statefull, there of course might be issues
