Incorrect security domain selected for web application.

I want to migrate from JBossAS 6 to 7.0.0.CR1. In standalone.xml I declare the following security domain, but get the stacktrace (see below) looking for UsersRolesLoginModule instead of DatabaseServerLoginModule.

Security domain in standalone.xml:
<security-domain name="swe2" cache-type="default">
<authentication>
<login-module code="Database" flag="required">
<module-option name="dsJndiName" value="java:/swe2DS"/>
<module-option name="unauthenticatedIdentity" value="gast"/>
<module-option name="principalsQuery" value="SELECT password FROM kunde WHERE username=?"/>
<module-option name="rolesQuery" value="SELECT role, 'Roles' FROM swe2_role r INNER JOIN kunde k ON r.kunde_fk = k.k_id WHERE k.username=?"/>
<module-option name="hashAlgorithm" value="SHA-1"/>
<module-option name="hashEncoding" value="base64"/>
</login-module>
</authentication>
</security-domain>

Stacktrace regarding UsersRolesLoginModule (instead of DatabaseServerLoginModule):
