I have tried to use projection to instantiate a DataModuleInfo passing a collection to his constructor but ReflectHelper.getConstructor for elements(dm.items) (a collection of ItemInfo) search for a constructor that require only one instance of ItemInfo:
I have tried other types instead of ItemInfo[] but debugging Hibernate I see that he require only ItemInfo.
