        // set to the calling application when the Home/Remote interfaces were
        // loaded from above the application classloader level.  
        //
        // Calling getClassLoader tests that the context classloader is set
        // appropriately because of the security requirements that J2SE
        // imposes on requesting a class loader.  By default application code
        // in the appserver does not have the RuntimePermission

        // allowed if the returned class loader matches the requesting 
        // class' class loader(or is a child of it).  So, if the context 
        // class loader is still incorrectly set to the calling app's 
        // class loader, the call to getContextClassLoader() should throw
        // a security exception.

        // javax.management APIs and this behavior is it will work on an
