Description

I am trying to implement extension bundles in the osgi container. We are using a wildfly and tomcat server. Starting the wildfly server with the added extension bundle causes the following errors:

It seems that it goes wrong in the extensionManager class around here:

ExtensionManager.class

try
            {
                extensionManager = new ExtensionManager();

                Felix.m_secureAction.addURLToURLClassLoader(Felix.m_secureAction.createURL(
                    Felix.m_secureAction.createURL(null, "http:", extensionManager),
                    "http://felix.extensions:9/", extensionManager),
                    Felix.class.getClassLoader());
            }

And in the the addURLtoIRLClassLoader it expects a urlclassloader but this is not provided because of wildfly/tomcat. That happens here:

SecureAction.class

public void addURLToURLClassLoader(URL extension, ClassLoader loader) throws Exception
    {
        if (System.getSecurityManager() != null)
        {
            Actions actions = (Actions) m_actions.get();
            actions.set(Actions.ADD_EXTENSION_URL_ACTION, extension, loader);
            try
            {
                AccessController.doPrivileged(actions, m_acc);
            }
            catch (PrivilegedActionException e)
            {
                throw e.getException();
            }
        }
        else
        {
            Method addURL =
                URLClassLoader.class.getDeclaredMethod("addURL",
                new Class[] {URL.class});
            addURL.setAccessible(true);
            addURL.invoke(loader, new Object[]{extension});
        }
    }

If you have any questions, let me know.
