More evidence that there is a bug: Meanwhile, I have made a test with an entity that contains an attribute of `MyEnum` annotated with `@Convert(converter=MyEnumConverter.class)`. This works as expected. The datatype in the database is `character(1)`.

Thinking more about it, the behavior that can be observed here is like if `@Enumerated(ORDINAL)` is present on the attribute, which is the default; i.e., it seems as if `@Convert(converter=MyEnumConverter.class)` is not considered.
