How to put a debug jar in a custom module to override classes in JBoss EAP 6

Issue

• EAP 6.x module questoins, how use debug.jar like did in EAP 5.x
• In EAP 5 we added to the classpath in the jboss-service.xml and would add a debug.jar which overrode our other classes for debugging purposes, we are migrating to EAP 6 and cerating custom modules, how can we put a debug.jar in our custom modules to override classes for debugging?
