Valid jboss-app.xml file fails to be parsed by jbossxb runtime. It works without problems on JBoss AS 4.x

The file content is:

<?xml version='1.0' encoding='UTF-8' ?>

<!DOCTYPE jboss-app
PUBLIC "-//JBoss//DTD J2EE Application 1.4//EN"
"http://www.jboss.org/j2ee/dtd/jboss-app_4_0.dtd">

<jboss-app>
<module-order>strict</module-order>
</jboss-app>

Here's the exception I'm getting:
