seam-registration examle from wolf test repo is incorrectly deployed

I am testing wolf repository (maven repo of EAP 5.1). There are several example projects. These examples depend on maven artifacts shipped by wolf repo. There is a problem with example called webapp-seam-registration. This example can be built and deployed using maven CLI (mvn install jboss:deploy). But .. when I import it into JBoss Tools using 'Import existing maven project' and then deploy it on EAP 5.1 I get deployment errors. I was comparing the deoplyed EARs and found out, that the problem is, that application.xml (contained in registration-ear project) does not contain

<module><ejb>jboss-seam.jar</ejb></module>

Deployment from CLI works fine ->application.xml has proper content
