------------------------------------------------------------

The problem is how to allow firing events with parameterized type as a payload and disallow firing events with type variables as a payload at the same time. AFAIK there is no way to resolve actual type arguments of parameterized type from its definition in runtime (this makes sense BTW). However it is possible to resolve actual type arguments of parametrized type if used in concrete method or field. In case of standard way of firing event (@Inject Event<Foo> foo...) the only solution seems to be to inspect its InjectionPoint. But I do not know of any suitable solution for *javax.enterprise.inject.spi.BeanManager.fireEvent(Object, Annotation...)*.
