@JsonSerialize(as=superType) behavior disallowed in 2.7.4 #1231
Description
#1178 fixed the problem with collections, but I'm seeing a problem with individual objects.
I'm getting:
com.fasterxml.jackson.databind.JsonMappingException: Failed to widen type [simple type, class org.pharmgkb.model.AccessionIdentifier] with annotation (value org.pharmgkb.model.BaseAccessionIdentifier), from 'getReference': Class org.pharmgkb.model.BaseAccessionIdentifier not a super-type of [simple type, class org.pharmgkb.model.AccessionIdentifier]

On something like:
public class Foo {
@JsonSerialize(as = BaseAccessionIdentifier.class)
@JsonDeserialize(as = BaseAccessionIdentifier.class)
public AccessionIdentifier getReference() {
}
}
public interface AccessionIdentifier {
}
public class BaseAccessionIdentifier implements AccessionIdentifier {
}
