Since [6d2af217aafd03e3f1600ce0ebc9c30cf0a7fc70#diff-3e45cf556c0330623c0167841d303dff](https://github.com/symfony/symfony/commit/6d2af217aafd03e3f1600ce0ebc9c30cf0a7fc70#diff-3e45cf556c0330623c0167841d303dff) the PropertyAccessor is failing on setters with default values because  [ReflectionFunctionAbstract::getNumberOfRequiredParameters](http://www.php.net/manual/es/reflectionfunctionabstract.getnumberofparameters.php) only count the parameters without default values.
