[weld-dev] Circular dependencies between dependent bean constructors

[Stuart Douglas]

Should this be detected as an error at deployment time? 

I don't think that letting a user run into a StackOverflowError is particularly friendly, but the spec does not explicitly state that the continer is required to detect this (unless I am missing something, which is often the case).

Well, exactly. I mean, that's obvious from the definition of an
@Dependent object, right?

I mean, I don't quite follow what the source of doubt here is. Section
6.4 is *very* explicit on this.
