Mapstruct does not map record parameters

[piotrekfus91]

Hi, I have a simple mapping to do (target class is generated from jsonschema, but in another maven module):

public record Codec(String codecString, String privateData) {
    public Codec {
        notBlank(codecString);
        notBlank(privateData);
    }
}

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({
    "codecString",
    "privateData"
})
public class CodecJson {

    /**
     * 
     * (Required)
     * 
     */
    @JsonProperty("codecString")
    @NotNull
    private String codecString;
    /**
     * 
     * (Required)
     * 
     */
    @JsonProperty("privateData")
    @NotNull
    private String privateData;
    @JsonIgnore
    @Valid
    private Map<String, Object> additionalProperties = new HashMap<String, Object>();

    /**
     * 
     * (Required)
     * 
     */
    @JsonProperty("codecString")
    public String getCodecString() {
        return codecString;
    }

    /**
     * 
     * (Required)
     * 
     */
    @JsonProperty("codecString")
    public void setCodecString(String codecString) {
        this.codecString = codecString;
    }

    public CodecJson withCodecString(String codecString) {
        this.codecString = codecString;
        return this;
    }
// remaining getters/setters are similar

When I make such mapping:

@Mapper(componentModel = "spring")
public interface PackagerParametersMapper {
    InitSegmentParametersJson map(InitSegmentParameters initSegmentParameters);

    CodecJson map(Codec codec);

I get:

@Override
    public CodecJson map(Codec codec) {
        if ( codec == null ) {
            return null;
        }

        CodecJson codecJson = new CodecJson();

        return codecJson;
    }

Expected behavior is to add both field values to returning codecJson. Am I correct? Mapstruct 1.4.2.
