Bug in WELD (CDI RI)

See WELD-2670

I can add multiple instances of a repeatable annotation on a method and/or on a stereotype used on that method, and the interceptor is triggered. I can freely mix both locations and then collect all annotations in my interceptor.

When I try to do the same at the class level, I run into two issues:

• If I add one instances of the same repeatable annotations on the class as well as on a stereotype used on the same class, I get an IllegalArgumentException: WELD-001312: Duplicate interceptor binding type QualifierInstance exception at deploy time. It works, if I put at least two instances of that annotation on the stereotype.

• If I add multiple instances of one repeatable annotation to a stereotype used at a class, the interceptor is simply not triggered.

Instructions

1. Build the war and deploy it on a WildFly 23.0.1.Final

2. Request http://localhost:8080/ping

3. Look into the logs ⇒ no messages from the interceptor.

4. Uncomment one of the @Logged annotations in the LoggedStereotype, rebuild/redeploy/rerequest ⇒ it logs.

5. Uncomment one of the @Logged annotations in the Boundary, rebuild/redeploy ⇒ Deployment fails.

6. You can repeat everything at the method level in the Boundary class by uncommenting there ⇒ everything works.
