public function ExceptionHandler::handle in Zircon Profile 8

Same name and namespace in other branches

1. 8.0 vendor/symfony/debug/ExceptionHandler.php \Symfony\Component\Debug\ExceptionHandler::handle()

Sends a response for the given Exception.

To be as fail-safe as possible, the exception is first handled by our simple exception handler, then by the user exception handler. The latter takes precedence and any output from the former is cancelled, if and only if nothing bad happens in this handling path.
