[BUG] delomboked class is missing @Builder.Default initialization in no args constructor

[Alexey007gold]

Describe the bug
There is a parent class

import lombok.AllArgsConstructor;
import lombok.NoArgsConstructor;
import lombok.experimental.SuperBuilder;

@SuperBuilder
@NoArgsConstructor
@AllArgsConstructor
public class DTOParent {
    private String a;
}

and a child, using @SuperBuilder and @Builder.Default

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.NoArgsConstructor;
import lombok.experimental.SuperBuilder;

@SuperBuilder
@NoArgsConstructor
@AllArgsConstructor
public class DTO extends DTOParent {
    @Builder.Default
    private Integer number = 5;
}

The problem is that lombok and delombok generate different result.
Lombok on the left and delombok+compile on the right

Expected behavior
Lombok initializes the field annotated with @Builder.Default in no-args constructor, as I believe is expected
Delomboked code is missing that step

Version info (please complete the following information):

• Lombok 1.18.22

How do you delombok? It looks like delombok uses Lombok <= 1.18.0.

How do you delombok? It looks like delombok uses Lombok <= 1.18.0.

> java -jar lombok.jar version
 v1.18.22 "Envious Ferret"
> java -jar lombok.jar delombok src/main/java -d src-delomboked

Screenshot in the issue description is showing two .class files, decompiled with Intellij. First one was compiled directly using lombok, the second one compiled from delomboked sources.

I still don't know how you managed to generate the code on the left side but I think that you actually found a bug. In 3987f54 support for @Builder.Default in @NoArgsConstructor was added. This works with javac if you use @Builder but not if you use @SuperBuilder. In ecj both annotations generate the initialization in the constructor so it most likely is an javac specific problem.
