> If Address is a component with a many-to-one with country, then the following hql results in invalid sql:
> from Person p join p.address a join a.country c where c.name is null
> The c.name is render as if the sql join had been rendered, which is correct.  However, the fragment "join a.country c" does not result in the physical sql join being produced which is incorrect.
> See org.hibernate.test.annotations.embedded.many2one.EmbeddableWithMany2OneTest#testJoinAcrossEmbedded as example
