It's working in weld 2.2.4.Final? I have a similar problem here and updated wildfly 8.1.0.Final to use weld 2.2.4.Final but is not working too.
I'm getting Can not set ClassA field ClassB.pessoaDAO to ClassA$Proxy$_$$_WeldSubclass.
ClassA is a CDI class with @Transactional and ClassB is a EJB with @Stateless and @LocalBean.
The ClassA is injected in ClassB.
ClassA and ClassB are groovy classes.
