Description

File: /typo3/sysext/core/Classes/Http/Message.php
Function: withHeader($name, $value)
Lines: 201...218

In this function we can see next code:

        if (!is_array($value) || !$this->arrayContainsOnlyStrings($value)) {
            throw new \InvalidArgumentException('Invalid header value for header "' . $name . '"". The value must be a string or an array of strings.', 1436717266);
        }

When I try this:

$file = BackendUtility::getRecord('sys_file', $id);
$response->withHeader('Content-Length', $file['size']);

I got exception: Invalid header value for header "Content-Length"". The value must be a string or an array of strings.

Yes, I know that I can convert int to the string. But int can be converted in string and I think this function should allow int values!
