Exception classes and their abstract should have common signatures

[neuberkauf]

Example:

/**
 * NotFoundHttpException constructor.
 *
 * @param string|null     $errorDescription
 * @param array           $errorData
 * @param string|null     $userTitle
 * @param null            $userMessage
 * @param array           $headers
 * @param \Exception|null $previous
 */

// Consistent signature
/**
 * AccessDeniedHttpException constructor.
 *
 * @param string|null     $errorDescription
 * @param array           $errorData
 * @param string|null     $userTitle
 * @param null            $userMessage
 * @param array           $headers
 * @param \Exception|null $previous
 */

/**
 * ServiceUnavailableHttpException constructor.
 *
 * @param int|null        $wait     // Pushes the signature out of alignment
 * @param string|null     $errorDescription
 * @param array           $errorData
 * @param string|null     $userTitle
 * @param null            $userMessage
 * @param array           $headers
 * @param \Exception|null $previous
 */

/**
 * HttpException constructor.
 *
 * @param int             $statusCode   // Provided by the child class
 * @param array           $httpHeaders  // Opposite end of the signature from the child
 * @param string          $error        // Internal (?) name for the error
 * @param string          $errorDescription  
 * @param array           $errorData
 * @param string          $userTitle
 * @param string          $userMessage
 * @param \Exception|null $previous
 */

Given the length of these signatures and different requirements, it may be more beneficial to provide the common Exception elements (message, code, previous), with an array of other values that can be checked for presence, requirement, type, etc.
