According to JLS 8.10 Record Declarations. The direct superclass type of a record class is java.lang.Record.

However, for primitive classes the value class inherits from the reference class, not java.lang.Record.

Example;


public class RecordTest {
    inline static record R(int x) {}

    public static void main(String... args) {
        R r = new R(10);
        System.out.println(r.x);
    }
}

>> javap 'RecordTest$R'
Compiled from "RecordTest.java"
final value class RecordTest$R extends RecordTest$R$ref {
  public final java.lang.String toString();
  public final int hashCode();
  public final boolean equals(java.lang.Object);
  public int x();
  static RecordTest$R RecordTest$R(int);
}

>> javap 'RecordTest$R.ref'
Compiled from "RecordTest.java"
abstract class RecordTest$R$ref extends java.lang.Record {
}
