Vincent Massol commented on CDI-114:
------------------------------------

{quote}Hmm, does it means xwiki is leaking cause previously injected values can be unregistered ("remove extension")?{quote}

Actually I don't know how we would behave if you remove at runtime a component that's been previously injected in another component. In theory yes there should be a problem.In practice in 12 years of XWiki I've never seen this happen.

{quote}Or did you mean you never inject the component by type but always Provider<X> everywhere? {quote}

No we don't do that systematically, although we recommend it. It's done mostly at places where it's important to be able to use the latest registered component for a given role.

{quote}If so you also do lazy validation which means you accept to start a not functional app cause of a missing component - CDI prevents it. Is that right?{quote}

Yes we do allow this.

Thanks
