> Since CDI 1.0 there is an inconsistency in the description of {{ProcessProducerMethod}} event...
> The text:
> {quote}
> For a producer method with method *return type X* of a bean with *bean class T*, the container must raise an event of type ProcessProducerMethod<T, X>.
> {quote}
> API:
> {code:java}
> /**
>  * @param <T> The return type of the producer method
>  * @param <X> The class of the bean declaring the producer method
>  */
> public interface ProcessProducerMethod<T, X> extends ProcessBean<X> {
> }
> {code}
> The same applies to {{ProcessProducerField}}. 
> TCK and RI (Weld) follow the API. As one of the consequences an {{ProcessProducerMethod<Foo,Producer>}} event is not delivered to an observer with the event parameter {{ProcessBean<Foo>}} - which is required by the spec but does not make sense at the same time.
> It's obvious that JCP compatibility rules required to keep the wrong ordering for CDI 1.x (see also the comments in {{javax.enterprise.inject.spi.ProcessProducerMethod}}). I believe this should be fixed in CDI 2.0.
