------------------------------------------------
Left a test to reproduce the issue.

> Issue Type: Bug
> Affects Versions: 3.0.0-beta1

> I'm using the Mapper API with a TypeConverter to convert a POJO field into
> and Instant/Timestamp column.
> However, the FieldAccessor code is very strict. It tries to find the binary
> mode directly from the original field type (in the POJO) instead of the
> target type of my TypeConverter.
