So here's the skinny: while my subclass was marked as serializable, the
parent class was not. So no state from the parent class got serialized nor,
not so surprisingly, deserialized. After adding that implements clause
things miraculously started working. So a big "you idiot" for me and a big
thanks to igor for pointing me to the Objects.cloneObject() method to help
write unit tests to highlight my otherwise obvious error.
