If a class member is not present in the input stream (for example, a private or protected member that was not defined as SERIALIZABLE), then that member is assigned its initial value.
If the input stream is unknown or cannot be read from, the AVM raises an error.
If the class of the object being deserialized changed between serialization and deserialization in a way that causes the object and its class to no longer match, the AVM raises an error.
The current position in the stream must be at the beginning of the data for the serialized object for the deserialization to complete successfully.
