Shared dependent instance injection with circular reference through decorator ----------------------------------------------------------------------------- Key: WELD-911 URL: https://issues.jboss.org/browse/WELD-911 Project: Weld Issue Type: Bug Components: Scopes & Contexts Affects Versions: 1.1.1.Final Reporter: Christian Bauer CDI spec section 6.4 says about @Dependent that "No injected instance of the bean is ever shared between multiple injection points."
