Reports the methods writeObject(), readObject(), readObjectNoData(), writeExternal(), and readExternal() or the field serialPersistentFields defined in a record class. These members are not used for the serialization or deserialization of records.

Examples:

  record R1() implements Serializable {
    // The field is ignored during record serialization
    @Serial
    private static final ObjectStreamField[] serialPersistentFields = new ObjectStreamField[0];

    // The method is ignored during record serialization
    @Serial
    private void writeObject(ObjectOutputStream out) throws IOException {
    }
  }

  record R2() implements Externalizable {
    // The method is ignored during record serialization
    @Override
    public void writeExternal(ObjectOutput out) throws IOException {
    }

    // The method is ignored during record serialization
    @Override
    public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException {
    }
  }

This inspection applies to the language level 14 or higher.
