Ah, the issue was that the implementation class had dependencies
effectively on itself:
@Named("tata") Osoba tata, @Mama Osoba mama
You probably don't want to use Guice at all on these objects. They seem
like simple bean-like data objects. Dependency injection is good for
wiring together the guts of your application, but it's best avoided for
data objects.
