Make Principal unwrappable -------------------------- Key: CDI-597 URL: https://issues.jboss.org/browse/CDI-597 Project: CDI Specification Issues Issue Type: Epic Reporter: Romain Manni-Bucau CDI allows to get injected a Principal but often you need to access the actual Principal instance when you need more than a name. Since the injection is a proxy (otherwise it would be broken in most of scoped wrapper instances cases) we would need a CDI solution to unwrap this instance. Solution I see without creating a new kind of API but just something specific to this case: CDIPrincipal extends Principal { <T> T unwrap(Class<T> t) } and allow to get it injected directly as Principal today. This issue can be linked to CDI-10 but here it is safe to add unwrap() where on CDI-10 it is not (too general).
