Pete Muir commented on WELD-994:
--------------------------------

Spec says "If a producer method or field of scope @Dependent returns an unserializable object for injection into an injection point that requires a passivation capable dependency, the container must throw an Illegal- ProductException"

In this case the Instance interposes, so the injection point is passivation capable. Just need to upgrade the checks in AbstractProducerBean.
