[hibernate-dev] Covariant returns

[Gunnar Morling]

Hi,

I see it the same way as you do; narrowing down the return type in the
implementation class shouldn't be a problem.

I'm also getting no compilation error when compiling the user's code
(as you said, IdentifierLoadAccessImpl shouldn't even be visible at
the call site). Maybe it's a problem with a certain
compiler/environment only?
