The expression return $this->em->getConnection()->executeQuery($this->sql, $parameters, $types, $this->queryCacheProfile) also could return the type Doctrine\DBAL\Driver\ResultStatement which includes types incompatible with the return type mandated by Doctrine\ORM\AbstractQuery::doExecute() of Doctrine\DBAL\Driver\Statement. Consider adding a type-check to rule them out.
