Hello,

We use SonarQube Community Edition * Version 9.4 (build 54424).

When we use subclass’s builder to build a instance, S3252 report a false postive.
Sample code
Base Class

@Data
@SuperBuilder(toBuilder = true)
@NoArgsConstructor
@JsonTypeInfo(use = JsonTypeInfo.Id.MINIMAL_CLASS)
public class BaseReferenceInfo {
}

Subclass

@Data
@SuperBuilder(toBuilder = true)
@AllArgsConstructor
@NoArgsConstructor
public class OpenMemoInfo extends BaseReferenceInfo {
    private long id;
    private String remarkType;
}

java:S3252 report issue on OpenMemoInfo.builder()

OpenMemoInfo.builder()
                    .id(memo.getId())
                    .remarkType(memo.getRemarkType())
                    .build()

Hello @willing_happy,

Thanks for the report! Indeed this would look like a false positive. I’ve not been able to reproduce the issue so far, however. Could you provide a small reproducer project in which you can observe the FP based on which we can investigate further?
