I am trying to write a JPQL query which returns a `boolean`, but even if I specify the result class as `Boolean.class` my query is still returning an object of type `BigDecimal`. 

    TypedQuery<Boolean> q = em.createQuery(
        "SELECT CASE WHEN ( count(e) > 0 ) THEN TRUE ELSE FALSE END"                        
                        + "FROM MyEntity e "
                        , Boolean.class);                         
        // Fails, because BigDecimal cannot be converted to Boolean
        return q.getSingleResult();
