JMS client is not working when initial context factory is loaded using JCL class loader

[sandrocsimas]

I'm trying to implement a JMS client using Weblogic implementation, but its not working correctly.
The inicial context factory class of Weblogic JMS implementation is weblogic.jndi.WLInitialContextFactory.
I was looking at the code and I found the reason it was not working. The class mentioned above is found by JCL, but for some reason, JCL is creating the instance in a different way of the class loader used by JMS, the context class loader.

// JMS is instantiating the initial context factory this way:
loadClass(className, getContextClassLoader())

// The code above call...
Class.forName(className, true, classLoader)

// Getting class loader:
ClassLoader getContextClassLoader() {
  return AccessController.doPrivileged(
    new PrivilegedAction<ClassLoader>() {
      public ClassLoader run() {
        ClassLoader loader = Thread.currentThread().getContextClassLoader();
        if (loader == null) {
          // Don't use bootstrap class loader directly!
          loader = ClassLoader.getSystemClassLoader();
        }
        return loader;
      }
    }
  );
}

Loading the initial context factory class using Thread.currentThread().getContextClassLoader() works fine. Using JCL class loader, the class is instantiated, but for some reason I could not connect to JMS server.
