Embedded in my question is, what is GSON used for at this stage? There are potentially three serialization mechanisms in play (java.io, Writable, GSON) and want to rationalize them. Is GSON still needed? (Could well be) 'transient' doesn't have meaning for Writable, though I take the point about annotation. But an annotation or comment could be a better thing. 'transient' in a non-Serializable class looks at first like a mistake.
