Exception with single quote literal

[tstauer]

Hi there,
I'm getting an error when a user supplies a single quote in my query.
My believe is that qomf->literal should escape the user input.

I'm using PHPCR with jackalope-doctrine-dbal and Symfony.

Here's my sample code:

use PHPCR\Query\QOM\QueryObjectModelFactoryInterface;
use PHPCR\Util\QOM\QueryBuilder;

        $jobId  = "'";
        $locale = 'de'
        $queryBuilder = new QueryBuilder($this->qomFactory);
        $qomf         = $queryBuilder->qomf();
        $queryBuilder->from(
            $qomf->selector('a', 'nt:unstructured')
        );
        $queryBuilder->where(
            $qomf->comparison(
                $qomf->propertyValue(
                    'a',
                    $this->propertyEncoder->localizedContentName('JobID', $locale)
                ),
                QueryObjectModelFactoryInterface::JCR_OPERATOR_EQUAL_TO,
                $qomf->literal($jobId)
            )
        );
        $qomQuery = $queryBuilder->getQuery();
        $queryBuilder->setMaxResults(1);
        $result = $queryBuilder->execute();

This is my error message:
An exception occurred while executing a query: SQLSTATE[HY000]: General error: 1105 XPATH syntax error: ')]) > 0'

I'm using these dependencies:

• jackalope/jackalope-doctrine-dbal 2.0.2
• jackalope/jackalope-jackrabbit 2.0.0
• doctrine/dbal 3.9.3

I found this:

• Binding string with apostrophe using QueryBuilder->literal() crash query doctrine/phpcr-odm#745
• https://github.com/phpcr/phpcr-utils/pull/224/files
  but that code is not even called in my example.

Could it be that https://github.com/jackalope/jackalope-doctrine-dbal/blob/2.0.2/src/Jackalope/Transport/DoctrineDBAL/Query/QOMWalker.php walkComparisonConstraint needs to escape single quotes?

Am I missing something here?
Thank you
