I think you can follow James' advice and subclass SimpleRichSequence, and then annotate it such that the awkward bits are not seralised.
Or, you can just extract the parameters of interest out of the original object and put them into some holding class (e.g. a simple HashMap) as I suggested and serialise that instead.
