Recently did a project where, for API purpose, we created an exception listener to transform those into specialized json responses.

The funny part is we now effectively disabled exception logging; discovered on prod :-) Because our custom response set, the built-in exception listener no longer runs; thus no logging.

The trick is to copy Symfony\Component\HttpKernel\EventListener\ExceptionListener::logException() and call as needed. Basically you need to dive into internals to figure it out.

Wondering... can we move the logException() logic and make it a (better) feature?
