Yep. I think this could be a nice improvement. I'll take a look.

> The RunMongoAggregation processor uses Jackson to serialize the document to
> JSON. However, the default serialization for Jackson on Mongo ObjectId and
> dates leaves a lot to be desired. The ObjectId's are serialized into the
> decimal representation of each component of the ObjectId instead of the hex
> string of the full byte array. Mongo dates are being serialized as unix time
> as opposed to ISO8601 zulu string.
> It looks like the GetMongo processor has set the correct serializer flags on
> Jackson to fix this. The fix for GetMongo is here.
