    Patterns adapted from https://coderwall.com/p/o--apg

    Known caveats:

    • If Jackson is instructed to deserialize a non-conforming numeric from a String, it will fail, e.g attempting to deser an Int from "hello". Conversely, if Jackson is instructed to deser a String from a numeric, it will succeed, e.g. "100" from 100. If an object has an obvious String representation, Jackson will attempt to treat it as such.
    • Null values will be treated as valid JSON. This is because null is a valid JSON value. Case classes that will be serialized/deser'd need to include their own validation to guard against unintentional nulls.
