TYPO3 Core

Hello Core-Team,

I have following yaml configuration for EXT:form:

...
finishers:
  -
    options:
      messageTitle: 'Argh'
      messageBody: 'I am sitting in the %s'
      messageArguments:
        - foo: 'bar'
      severity: -1
    identifier: FlashMessage
...

This will result in following error message:

Argument 1 passed to TYPO3\CMS\Core\Messaging\AbstractMessage::setSeverity() must be of the type integer, string given, called in /Users/stefan/htdocs/typo3_src/typo3/sysext/core/Classes/Messaging/FlashMessage.php on line 42

I have defined that value as int and it is still int while calling FlashMessageFinisher, but there is no early return for options of type int, so severity lands in your preg_replace_callback(whatever) and will be returned as string, which, of cause, is not valid.
