> When using an Adapter on a data type field where the "arrayity" of the field changes, such as the case of `byte[]` to `String` adapter (such as serializing binary as hexadecimal instead of base64)
> Mapper works without issue when deserializing/reading the data, but causes an IllegalArgumentException "This is not an array" when attempting to serialize the object.
> This seems to be related to how the mapper reader caches the field's "arrayity" and does not expect/allow it to be changed by an adapter/converter.
> Small junit suite that reproduces the functioning deserialization and failing serialization is attached.
