ClassCastException validating custom Interceptor implementation
---------------------------------------------------------------

                 Key: WELD-996
                 URL: https://issues.jboss.org/browse/WELD-996
             Project: Weld
          Issue Type: Bug
    Affects Versions: 1.1.2.Final
            Reporter: Jozef Hartinger
            Priority: Critical
             Fix For: 1.2.0.Beta1


Having a custom implementation of the Interceptor interface registered with Weld, the validation always fails if the interceptor happens to intercept a passivation capable bean. Weld incorrectly casts the interceptor to InterceptorImpl which is not valid for extension-provided interceptors.
