Получение ошибки 'java.lang.ClassCastException: java.util.Date не может быть приведен к java.lang.String'

У меня ниже метод обновления столбцов в 3 таблицах. Записи обновляются в первой таблице (Ref: query2) успешно, но она дает ошибку при обновлении столбца "modifiedDate" в таблице 2 и таблице 3. Тот же столбец успешно обновлен в таблице 1.

@Override
    public void updateResult(int candidateID, String newResult, int totalScore, Date today, String newUploadState) {

        System.out.println("Updating the result to DB");

        Session currentSession = sessionFactory.getCurrentSession();

        String query1 = "SELECT p.ro  FROM PersonalInfo p WHERE p.candidateID =:id";

        String ro = currentSession.createQuery(query1).setParameter("id", candidateID).list().get(0).toString();

        String query2 = "UPDATE PersonalInfo as p set " +
                        "p.score = :score," +
                        "p.result = :result, " +
                        "p.modifiedDate = :modifiedDate, " +
                        "p.modifiedBy = :modifiedBy, " +
                        "p.uploadState = :uploadState " +  
                        "where p.candidateID = :id";

        Query thequery2 = currentSession.createQuery(query2);
        thequery2.setParameter("id", candidateID);
        thequery2.setParameter("score", totalScore);
        thequery2.setParameter("result", newResult);
        thequery2.setParameter("modifiedDate", today);
        thequery2.setParameter("modifiedBy", ro);
        thequery2.setParameter("uploadState", newUploadState);
        thequery2.executeUpdate();

        String query3 = "UPDATE Address as a set " +
                "a.modifiedDate = :modifiedDate, " +
                "a.modifiedBy = :modifiedBy, " +
                "a.uploadState = :uploadState " +  
                "where a.candidateID_FK = :id";

        Query thequery3 = currentSession.createQuery(query3);
        thequery3.setParameter("id", candidateID);
        thequery3.setParameter("modifiedDate", today);
        thequery3.setParameter("modifiedBy", ro);
        thequery3.setParameter("uploadState", newUploadState);
        thequery3.executeUpdate();

        String query4 = "UPDATE Fitness as f set " +
                "f.modifiedDate = :modifiedDate, " +
                "f.modifiedBy = :modifiedBy, " +
                "f.uploadState = :uploadState " +  
                "where f.candidateID_FK1 = :id";

        Query thequery4 = currentSession.createQuery(query4);
        thequery4.setParameter("id", candidateID);
        thequery4.setParameter("modifiedDate", today);
        thequery4.setParameter("modifiedBy", ro);
        thequery4.setParameter("uploadState", newUploadState);
        thequery4.executeUpdate();
    }

Ниже показана трассировка стека с консоли, которая показывает ошибку, связанную с литой даты в String. Тип данных для столбца ModifiedDate во всех трех таблицах - "datetime".

Hibernate: update personal_info set Score=?, Result=?, ModifiedDate=?, ModifiedBy=?, UploadState=? where CandidateID=?
