As I understood it, when accessed through the Session interface what
return type is defined by SessionImpl is irrelevant. And indeed I am
not able to reproduce this when access those methods via Session. My
IDE gives me errors if I try to cast that reference to SessionImpl
instead.
I tested it quickly in the test case I was working on and I confirm it
works (with the Eclipse compiler and directly with Maven and the
Oracle JDK 1.6.30 compiler).
That said, I don't understand why you return the Impl instead of the
interface: it's not consistent with byNaturalId() and
bySimpleNaturalId() which are just below. Is there any reason why you
treated them differently?
