Почему Spring Data делает лишние запросы?

Есть следующий метод JPA репозитория:

@Query("select new com.example.sweater.domain.dto.MessageDto(" +
            "   m, " +
            "   count(ml), " +
            "   sum(case when ml = :user then 1 else 0 end) > 0" +
            ") " +
            "from Message m left join m.likes ml " +
            "group by m")
    Page<MessageDto> findAll(Pageable pageable, @Param("user") User user);

Проблема: вместо одного запроса, который указан в аннотации @Query, в базу еще летят запросы на выборку КАЖДОГО сообщения отдельно.
Вопрос: почему так происходит и как с этим бороться?
Весь код доступен на github
UPD1: лог запросов:

UPD2: Еще заметил, что когда я пытаюсь передать в MessageDto(m,...), то вместо m передается не объект сообщения, как мне надо, а id этого сообщения. Может по этому hibernate ходит в базу за каждым сообщением?
