Summary: 0005511: unserialize() fails with IOException when unserializing PHP class the implements Serializabe
Description: When I attempt to unserialize objects that implement the PHP Serializable interface Quercus throws:

I looked at the UnserializeReader.unserialize(...) method and the case statement does not account for 'C' as the leading character of the serialized string. The PHP doc on the Serializable interface (http://php.net/manual/en/class.serializable.php) [^] shows that this is a valid leading character.

The serialized objects were written to disk using PHP 5.3.
