 To get around this behavior, you would simply need to extend the ``ExceptionListener``
-class and override the default method named ``setTargetPath()``.
-
-First, override the ``security.exception_listener.class`` parameter in your
-configuration file. This can be done from your main configuration file (in
-``app/config``) or from a configuration file being imported from a bundle:
-
-.. configuration-block::

-        .. code-block:: yaml

-            # app/config/services.yml
-            parameters:

-                security.exception_listener.class: AppBundle\Security\Firewall\ExceptionListener

-            <parameters>
-                <!-- ... -->
-                <parameter key="security.exception_listener.class">AppBundle\Security\Firewall\ExceptionListener</parameter>
-            </parameters>

-
-            // ...
-            $container->setParameter('security.exception_listener.class', ExceptionListener::class);

+Next, create the ``ExceptionListenerPass`` to replace the definition of the default
+``ExceptionListener`` with the one you just created. Make sure to use the name of

+
+    // src/AppBundle/DependencyInjection/Compiler/ExceptionListenerPass.php

+            $definition->setClass(ExceptionListener::class);
+        }

+Finally, add a compiler pass to tie it all together::

+    namespace AppBundle;
+    
+    use AppBundle\DependencyInjection\Compiler\ExceptionListenerPass;
+
