Extending class gives unexpected behaviour

Question

Hello forumusers
I am making my own table model by extending DefaultTableModel. When calling insertRow(int, Object[]) in my own code, super.insertRow calls insertRow(int, Vector) in my code instead of in the superclass. I didn't think that the superclass would hold any reference to my class and when the superclass calls insertRow(int, Vector) it would be a method in the DefaultTableModel class.
Please see the code below. Can anyone explain this behaviour to me?
import java.awt.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;
class TableModelTest {
  public TableModelTest() {
    BundleTableModel m = new BundleTableModel(
        new String[][]{{"aaa", "aab", "aba"}, {"ccc", "cca", "cac"}},
        new String [] {"header0", "header1", "header2"});
    m.insertRow(1, new String[]{"BBB", "BBA", "BAB"});
  public static void main(String[] args) {
    TableModelTest dut = new TableModelTest();
  public class BundleTableModel extends DefaultTableModel {
    public BundleTableModel(String[][] dataIds, String[] columnNameIds) {
      super();
      setColumnCount(columnNameIds.length);
      setRowCount(dataIds.length);
      // My own code comes here
    public void insertRow(int row, Object[] rowData) {
      System.out.println("insertRow(int, Object[] called");
      super.insertRow(row, rowData);
      // My own code comes here
    public void insertRow(int row, Vector rowData) {
      System.out.println("insertRow(int, Vector) called");
      super.insertRow(row, rowData);
      // My own code comes here
}

Lesson learned.
ejp was correct from the beginning.
JLS section 8.4.10.6 'Large Example of Overriding' explains:
"The critical point about overriding in this example is that the method putstr, which is declared in class BufferOutput, invokes the putchar method defined by the *current object this*, which is not necessarily the putchar method declared in class BufferOutput.
This allows a subclass of BufferOutput to change the behavior of the putstr method without redefining it."
Thanks for all comments.
