@JsonCreator annotated factory method not used when wrapping value object

[wimdeblauwe]

I am using Jackson 2.12.3 and it seems that Jackson will sometimes take preference for a private constructor over a public static factory method that is annotated with @JsonCreator.

This example showcases the problem:

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.module.paramnames.ParameterNamesModule;

import java.io.IOException;

public class Test {
    public static void main(String[] args) throws IOException {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.registerModule(new ParameterNamesModule());
        ValueObject valueObject = objectMapper.readValue("{\"value\":\"ABC-123\"}", ValueObject.class);
        System.out.println("valueObject = " + valueObject);
        System.out.println("----");
        WrapperObject wrapperObject = objectMapper.readValue("{\"valueObject\":\"ABC-123\"}", WrapperObject.class);
        System.out.println("wrapperObject = " + wrapperObject);
    }

    public static class ValueObject {
        private final String value;

        private ValueObject(String value) {
            System.out.println("constructor: " + value);
            this.value = value;
        }

        @JsonCreator
        public static ValueObject of(String value) {
            System.out.println("factory: " + value);
            return new ValueObject(value);
        }

        public String getValue() {
            return value;
        }
    }

    public static class WrapperObject {
        private final ValueObject valueObject;

        @JsonCreator
        public WrapperObject(ValueObject valueObject) {
            this.valueObject = valueObject;
        }

        public ValueObject getValueObject() {
            return valueObject;
        }
    }
}

Running this (on Java 11) outputs:

factory: ABC-123
constructor: ABC-123
valueObject = be.fodjustitie.inventaris.inventarisbackend.Test$ValueObject@2a3b5b47
----
constructor: ABC-123
wrapperObject = be.fodjustitie.inventaris.inventarisbackend.Test$WrapperObject@799f10e1

So you can see when deserializing WrapperObject, the factory is not used which I would not expect given the factory method is annotated with @JsonCreator.

This might be related to #660 and/or #2135, not sure.
