Re: [cdi-dev] Regarding annotations

[Emily Jiang <emijiang6@xxxxxxxxxxxxxx>]

Straightly speaking, if you attach an interceptor on the bean with `@Singleton`, you will get a proxy, right @Matej Novotny ?

I would be -1 to remove Singleton, I see it used pretty commonly. The main difference from app scoped is that while they are both "one instance per container", application scope uses proxies, whereas singleton doesn't.
This usually doesn't matter, but there are cases (more prominent in build time environment, or when it comes to serialization, or where you want lazy init, ...) in which the difference matters and being able to choose is nice.
If anything, I would rather add Singleton as a bean defining annotation into CDI.

+1 for that latter, and make it clear in the documentation that in CDI @Singleton is not proxied, where @ApplicationScoped is.

Kind regards,

Arjan
