The spec states in 6.6.4. "Validation of passivation capable beans and dependencies":

If a bean which declares a passivating scope type, or any stateful session bean, has a decorator or interceptor which is not a
passivation capable dependency, the container automatically detects the problem and treats it as a deployment problem.

WRT CDI-136 "If a bean which declares a passivating scope type, or any stateful session bean," should be replaced with: "If a managed bean or stateful session bean which declares a passivating scope".

I'm not sure about the wording "has a decorator or interceptor which is not a passivation capable dependency" because the wording in section 6.6.1. "Passivation capable beans" is "interceptors and decorators of the bean are passivation capable" (passivation capable dependency vs passivation capable).
