The cause of the failure is that ClassPoolDomain was not copying the structure of a domain when the domain's parent is a ClassLoaderToLoader adapter. I have committed a temporary ugly hack, but I need to figure out how can I retrieve the classLoader in this scenario: if (domain.getParent() instanceof ClassLoaderToLoaderAdapter) | { | // how to get the domain.getParent()'s classloader??? | ClassLoader loader = ...; | ClassPool parentPool = ClassPoolRepository.getInstance().registerClassLoader(loader); | poolDomain = new JBossClClassPoolDomain(domain.getName(), parentPool, domain.getParentPolicy(), registry); | } View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4262546#...
