Answer 1

Even it's a little bit late but never too late, You make your normal projection with a list inside then in the end it's possible in hibernate to return one line using this :

.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY)

Details here: Criteria.DISTINCT_ROOT_ENTITY vs Projections.distinct
