Aleksandr Mashchenko commented on WW-5089:
------------------------------------------
I'm no 100% sure about this, but I think the cdi plugin by default doesn't
create a full-blown bean out of actions. It allows injections to actions, but
that's it. Annotations and @PreDestroy are not going to work on actions unless
you create a proper bean out of it by yourself.
[~bartlomiej-kfn]
Try to create a bean from action with @RequestScoped and *use* it, then
@PreDestroy on your CDIBean should work.
> @PreDestroy callbacks not invoked on injected beans
