Of course this might be an error in OWB.
But I generally question the reason why one would like to create a EntityManager for a PersistenceUnit
with no name. That would not allow you to use this mechanism in a bit more complex scenarios...

AFAICS Seam adds the bean for the EntityManager in: org.jboss.seam.persistence.ManagedPersistenceContextExtension.registerManagedPersistenceContext
/ afterBeanDiscovery
This bean is also added with OWB but why it will not be injected?

Don't know how seam produces the EntityManager but the configuration is correct.
You can read about it here:

I don't know anything about JPA, but this field produces a
EntityManagerFactory while you inject an EntityManager.  You'd need to
either uses a producer method that invokes the factory, or inject the
factory and then invoke it.
