If that's not the case, you should use 'select distinct'. That said, we might want a way to recover the old behavior (H5, apparently) of making things distinct in memory according to equals(). Though, actually, I believe you can just use a ResultListTransformer for that. Perhaps we should just add a built-in one for migration purposes.
