And.. not a strong preference but maybe put this in `JacksonUtils` and
rename it `JsonUtils` if @cloud-fan is okay?
Maybe we could throws an exception as `IlligalArgumentException` in the
first place and then capture the message with `AnalysisException` (as
`JacksonUtils.verifySchema` is doing in `StructToJson`). This is not a strong
opinion too.
