php5 beta3 preg_replace_callback() change?

Hi All, I wanted to check if something changed in the preg_replace_callback() function. After going to beta3 we are now not able to make static object/method calls, that were working on beta2. Here is the error message: Warning: preg_replace_callback(): requires argument 2, 'self::replacePropertyCallback', to be a valid callback in /usr/local/phing/classes/phing/parser/ProjectConfigurator.php on line 202 Thanks, David
