From Alec: if you get a parse error like this, there is no sense retrying the message, because the message is not going to change. It's equivalent to a 400 error – retrying it isn't going to make a difference. So I would suggest here throwing an error whiel also acking (not nacking) the message to move on in this case (leaving nacks in other cases which may be retryable).
