Unable to deploy old EAP 5 SAR in JBoss EAP 6.0.x

Issue

• Our application uses jbosscommonj.sar to create Timer & WorkManager. JBoss commonj implementation: http://commonj.myfoo.de. We are moving to JBoss EAP 6 and we are unable to deploy the SAR. I created a module com.commonj that contains the commonj code, but we are getting the below error during deployment:

• When I deployed old EAP 5 SAR in EAP 6.0.x, deployment failed with the following ClassNotFoundException:
