Re: [hibernate-dev] UserCollectionType mapping for Ceylon
Ah, OK, thanks for the link, Vlad, now I think I sorta maybe see why.
With XML-based mappings, the semantic "kind" of collection is explicit
(<list/> or <set/> or whatever) whereas with annotations that is
determined by looking at the property type. The UserCollectionType
doesn't actually have this information.
So then I guess I'm going to need a bit of a deeper hack to make this work.

I think that only the Java Collection types work with the JPA
@OneToMany
associations, as it's described int his issue:
https://hibernate.atlassian.net/browse/HHH-4417
So, even when specifying a @CollectionType, the return type must be a
List/Set:
@OneToMany(...)
@CollectionType( type="MyCustomListType" )
public List getOrders()
