Lukasz Lenart commented on WW-5089:
-----------------------------------
Right, I wonder how to properly resolve that. Should we just point out in the
docs this case or maybe somehow change the CDI factory, but in such case action
isn't CDI managed and I don't know how this should work.
> @PreDestroy callbacks not invoked on injected beans
