Yes you are right. 3.3.7 actually only talks about 'producer methods' > 3.3.7.

I've created https://issues.jboss.org/browse/CDI-145 in the spec issue tracker. Gerhard, I also think that it works in OWB, but it's not really spec conform and might have rough edges ;) So we should also move our example to using producer methods.
