Having a meta-annotation using @Column and the @Column itself brings undefined behavior, and only one annotation (the one that does not define the custom value converter) gets used here.
Merging annotations was considered when implementing meta-annotations, but it is also fragile and non-intuitive, so we just pick one annotation and go with it.
It is strongly recommended to only use one of the (meta-annotation, @Column annotation).
