Description

The comment for the method \TYPO3\CMS\Core\Cache\Backend\SimpleFileBackend::setCacheDirectory() states clearly, that it is possible to provide an absolute path as cache directory. However, in the lower part of the function, it is stated, that if ($cacheDirectory0 == '/') the documentRoot should be set to '/'. That results in a returned path like '//...'.
This causes problems within \TYPO3\CMS\Core\Utility\GeneralUtility::validPathStr(), because pathes with '//' in it are always invalid.
So my suggestion would be to set the documentRoot to '' if the condition is true.
