Here is the problem.

I've got @Typed class becouse I wanted to limit the set of proxies generated by weld becouse it's ancestors would not be proxyable. That's why I tried @Typed. And halfway it works. But just halfway. The problem I notice is here in Validator (lines 142-145)

if (normalScoped && !Beans.isBeanProxyable(bean))

My @Typed class which is annotated like this:

@Named("catalogEntityHome")
@ConversationScoped
@Typed(CatalogEntityHome.class)
public class CatalogEntityHome extends BasicDAO<CatalogEntity, ObjectId> implements Serializable {
..

The problem I observe is that Beans.isBeanProxyable checks Proxies.getUnproxyableTypesException(bean) which somehow produces non-null result. However a moment later it checks Proxies.getUnprox....(bean.getTypes()), which turns to be null. And that's what it tries to throw, like here:
