Why are Sub deployments in ear are not isolated in JBoss EAP 6

Issue

• How does the classloading works in the ejb-in-ear example? When the GreeterEJB is referenced from the web module it can be injected without (from what I can see) any dependencies specified in a jboss-deployment-structure.xml or similar. I was under the impression that you had to do this in JBoss EAP 6 since the modules (ejb and web in this case) have separate classloaders? So I'm a bit confused as to how the dependency can work with just a "provided" dependency in the pom.xml of the web module. Is it using the parent class loader (ear) automatically somehow?
