Do not report 'convert to record'for classes that are extended from

False positive: Records should be used instead of ordinary classes when representing immutable data structure (S6206)

SonarLint plugin for IntelliJ connected to project

A Java class cannot extend a record, as records are final classes. Sonar still reports that the superclass should be converted to a record.

minimal example:

public class A {
    private final int i;

    public A(final int i) {
        this.i = i;

    public int getI() {
        return i;

public class B extends A {
    public B(final int j) {

SonarLint reports a major Code Smell about converting class A to a record, which would be valid if class B did not extend A.

Hey @kistlers ,
Thank you for reporting this. While it is easy for our analyzer to find the classes A inherits from, it is not possible, at acceptable cost, to get all child classes.

As a lot of developers moving to more recent versions of Java are likely to hit the same issue, I created a ticket to limit the scope to classes that are marked as final.
