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.
