What I currently lack is a map from Modules to ClassPools. I guess I'll create a JBossClDelegatingCPRepository (BTW, maybe we should refactor those names?) and add a unregister(ClassLoader, Module) like the one below: public void unregisterClassLoader(ClassLoader classLoader, Module module){ | ClassPool classPool = registeredModules.remove(module); // remove from the newly created map module->classpool | if (classLoader == null) | classPool.close(); // perform CP cleanup | else | this.unregisterClassLoader(classLoader); // needs to call the original unregister module so | // that the registeredCLs mapping is cleaned up as well; this method also invokes classPool.close() | // and this should not be done twice | } View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4265322#...
