The "deployment" you are talking about doesn't go through the deployers at all, so there is no POST_CLASSLOADER or REAL. It is a part of the bootstrap "before" the deployers exist. For something that does go through the deployers, you shouldn't use the MC "classloader" element, you should use a META-INF/jboss-classloading.xml that the deployers know about.
