Romain Manni-Bucau commented on CDI-597:

[~arjant] it is in JAAS so should be supported somehow (but LoginContext is not mandatory). +100 to move it to security spec. That said it means principal injection moves too since today it is in CDI (shouldn't have been I agree)

> 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).
