Adding onto the JTA list since we need this issue clarified as part of the
discussion on the closing the JTA 1.2 MR.
I'm equally interested in the discussion around the question Joe asks
about *how* interceptors are supposed to be involved in non-contextual
references.

Ian

I've even quoted it to customers a few times. If CDI isn't given an
opportunity to participate in the creation of the instance (i.e. non
contextual instance), how would the container have a hook point to be able
to run interceptors when methods are called on that instance?

between JTA and CDI: servlets, JAX-RS resource classes, and JAX-WS service
endpoints are created by their containers with non-contextual references
(according to the platform specification EE 5.24 and in our
implementation) but the CDI spec (section 7.2) precludes bean with
non-contextual references from being intercepted:

be changed to be consistent?
