No really. Weld stores the bindings also in context data but the API is using a direct reference to a stored set.

Ah, ok, thx

Going via getContextData() is much easier though for code that has to support both Weld and OWB.

Yep, standardizing the key is the only viable solution without interceptors spec change. However, it's not typesafe, easy-to-use, etc.

I hear you. The question is when the earliest opportunity will be to update the interceptor spec then. With the whole Java EE transfer I guess this will have to wait at least until that transfer is complete. Hopefully in the new process we can have something like a hierarchical responsibility for specs, such that if e.g. Interceptors and AtInject is not explicitly open, but CDI is, that the CDI EG can take responsibility for it and make changes there.

For now though, if OWB could also store the bindings under some key, interceptors that are intended to be portable can practically check both keys then. Not ideal, but may be a good intermediate solution.

And this is obviously wrong. Recently, we've reviewed a Narayana PR which is about to fix this problem:

I personally think that JTA TCK is missing some essential tests here.

Agreed, and the Java EE Security TCK misses those same tests as well, as it also ships with interceptors.

I don't think this is an InterceptionFactory-specific problem. It's a general issue. It should work the same if you use an extension to add an interceptor binding.

You're right, the InterceptionFactory just brought it to the surface again for people testing CDI 2.0 features.

Handling stereotypes as per the issue can be a problem as well. I wonder, wouldn't it be convenient if CDI offers a utility method to look for an annotation where it would automatically recurses into stereotypes?

I created something like for OmniFaces a while ago:

        Is there a standard way to get the bindings? Perhaps getting
        hold of the Bean<T> that represents the current Interceptor?

    You can inject a bean with scope @Dependent, qualifier @Default and
    type Interceptor into any interceptor instance. However, this will
    not help for @Nonbinding value members of an interceptor binding.
