Romain Manni-Bucau resolved JOHNZON-227.
----------------------------------------
Resolution: Fixed
Assignee: Romain Manni-Bucau
Fix Version/s: 1.1.14
Note: fixed by enabling dynamic mode, we can revisit that solution to
introspect adapters if there is any perf concern - but since it is very local
it should be ok.

> 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.
