I'll ask him tonight. But I think he came across this issue when
writing demo code for the new edition of his java EE book :-)

CDI has 2 implementation and both provides proprietary Java SE support. Perhaps it's possible to provide guidelines to integrate Weld or OWB thru their specific SE bootstrap system in ACC implementation. It won't be at the specification level so it'll have no impact on CDI spec but we'll provide an effective solution to boot Weld or OWB in a given ACC until next EE version. I guess EE EG won't be bvery happy with it but It's better than nothing.
