SpringBoot @RequestBody validation of abstract class

I am trying to simulate the oneOf construct from OpenAPI spec in my spring-boot application. I have an abstract class Apple

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, property = "color")
@JsonSubTypes({
        @JsonSubTypes.Type(value = RedApple.class, name = "RED"),
        @JsonSubTypes.Type(value = GreenApple.class, name = "GREEN")
})
public abstract class Apple {

    @NotNull
    private Color color;

    public Color getColor() {
        return color;
    }

    public void setColor(Color color) {
        this.color = color;
    }

    public enum Color {
        RED, GREEN
    }
}

and two subclasses

public class RedApple extends Apple {

}

public class GreenApple extends Apple {

}

Also here is my rest controller

@RestController
@RequestMapping("/apples")
public class AppleController {

    @PostMapping
    public ResponseEntity<Void> createApple(@Valid @RequestBody Apple apple) {
        return ResponseEntity.created(URI.create("/foo")).build();
    }
}

The problem is that @Valid does not validate the enum field correctly. Even if I send {"color": "RED"} as a body, the validation fails with a message saying that color must not be null

When I do the exact same thing with a non-abstract class and without JsonSubTypes & JsonTypeInfo annotations everything works like a charm. What am I missing here?

Thanks

adding visible = true as parameter to the JsonTypeInfo solved the issue @JsonTypeInfo(use = JsonTypeInfo.Id.NAME, visible = true, property = "color")
