Critical Description
LoggerConfigurationAdapterINI uses INI_SCANNER_RAW option when calling parse_ini_file().
This option was introduced in PHP 5.3. and the result is that parsing of INI config files failes when using php 5.2.x.
To keep backward compatibility, this option should be removed. Special care should be taken that option parsing is not affected. Especially since parse_ini_file() without the RAW option produces some unexpected results (check LoggerOptionConverter).
