When I use CertificateRoles module in AS7 configuration and specify a path to roles.properties like this:
<module-option name="rolesProperties" value="${jboss.server.config.dir}/roles.properties"/>
,the server throws the following error:

ERROR [org.jboss.security.auth.spi.CertRolesLoginModule] (http-/127.0.0.1:8443-1) Failed to load users/passwords/role files: java.io.IOException: No properties file: ${jboss.server.config.dir}/roles.properties or defaults: defaultRoles.properties found

However, when I put the absolute path to that file, it is found. This is noticeable difference from UsersRoles module where it works as expected. The problem is in class picketbox/security-jboss-sx/jbosssx/src/main/java/org/jboss/security/auth/spi/CertRolesLoginModule.java
