The POJO subsytem isn't setting the TCCL (Thread.currentThread().getContextClassLoader()) to the application's class loader while invoking on the application's lifecycle methods. The TCCL is set to the "ModuleClassLoader for Module "org.jboss.as.pojo:main" from local module loader".
It was working in JBoss5.1 to start a bean with an xml file (<deployment xmlns="urn:jboss:bean-deployer:2.0"> ...) and to use the TCCL during deployment to load resources and classes from the ear. With the pojo ModuleClassLoader these resources are not found.
