------------------------------------------------------------
1. I assume you are talking about sun.misc.URLClassPath and not sun.misc.URL
(which doesn't exists as far as I can see).
2. I'm not sure this is related to the ExtensionManager as such. What makes you
think so?
3. It would help if you had a stacktrace for the exception. My guess is it is
failing to create a url for some reason. The question is what does that url
look like.
4. What version of felix are you using? Can you try with the current trunk?

> URL: https://issues.apache.org/jira/browse/FELIX-3696
> Project: Felix
> Issue Type: Bug
> Affects Versions: framework-4.0.2
> Reporter: Miguel Ángel Pastor Olivar
>
> I am embedding Apache Felix (and Equinox because I would like to switch
> depending on the application server I am running on).
> * The xalan ExtensionHandler executes something like this:
> ObjectFactory.findProviderClass(className, ObjectFactory.findClassLoader(),
> true)
> * The className has the format
> "java:org.portletbridge.portlet.BridgeFunctions" ( I am embedding the OSGI
> container into Liferay portal :) )
> * The extension manager have already added the extension loader to the
> classloader
> {code}
>
> Felix.m_secureAction.addURLToURLClassLoader(Felix.m_secureAction.createURL(Felix.m_secureAction.createURL(null,
> "http:", extensionManager),"http://felix.extensions:9/";,
> extensionManager),Felix.class.getClassLoader());
> {code}
> * When the classloader try to resolve the
> "java:org.portletbridge.portlet.BridgeFunctions" the previous loader added by
> the ExtensionManager cause an unhandled error.
> In sun.misc.URL
> {code}
> public Resource getResource(String name, boolean check) {
> if (DEBUG) {
> System.err.println("URLClassPath.getResource(\"" + name + "\")");
> }
> Loader loader;
> for (int i = 0; (loader = getLoader(i)) != null; i++) {
> Resource res = loader.getResource(name, check);
> if (res != null) {
> return res;
> }
> }
> return null;
> }
> {code}
> In the previous code, the loader injected by the framework is causing an
> IllegalArgumentException here:
> Resource res = loader.getResource(name, check); (instead of returning null)
> Let me know if you need some more details.
