      If an EJB client tries to use @EJB to inject an EJB Local Proxy and the Local interface is in two different classloaders/modules/sub-deployments, it throws the error below. It would be helpful for the user to identify the issue if the exception indicated multiple classloaders or class HelloWorld is loaded from multiple modules or class cast exception.
