Hi, This is split-off from the thread "Bean<T> that only qualifies super types?", where the question came up what a Bean<T> should return from the getBeanClass() method for the case of build-in beans. The JavaDoc for getBeanClass() currently says the following: "The bean class of the managed bean or session bean or of the bean that declares the producer method or field." See: https://javaee-spec.java.net/nonav/javadocs/javax/enterprise/inject/spi/B... The case where a Bean<T> instance is directly created and added as bean to AfterBeanDiscovery in an extension does not seem to be covered by this documentation. Weld returns "this.class" here. See http://grepcode.com/file/repo1.maven.org/maven2/org.jboss.weld.se/weld-se... Is that what build-in beans should always do, and if so, should the JavaDoc/spec be clarified for this?

please create a new spec issue. This should be definitely clarified.

So given: public abstract class AbstractClass implements Interface { ... } If getTypes returns only Abstract.class, then only the methods defined by AbstractClass itself are implemented by the proxy. Those from Interface throw exceptions when called. If getTypes returns both Abstract.class and Interface.class, then all methods defined by AbstractClass and Interface are implemented by the proxy. Is this how things should be, or should the proxy generator see for itself that AbstractClass implements Interface?
