*
* Since backwards compatibility for objects stored in ParserCache is necessary,
* failure of a deserialization test most likely indicates an error in the code.
* However, since the serialization format may change, thus if proper compatibility
* logic was added but a serialization test is still failing, you might want to
* update stored serialized data using validateParserCacheSerializationTestData.php

* to generate and save serialized object, which would be used for acceptance
* deserialization tests.
