Java TableCellListener导致数组索引越界错误

我编写了一个使用

TableCellListener

类的程序

代码可以正确编译，但当我运行程序时，使用Tab键从一个单元格导航到另一个单元格时，会出现以下错误：

只有在使用Tab键时才会发生这种情况。如果我用鼠标，这个程序运行得很好。另一个用户在他的计算机上运行了完全相同的程序，无法复制问题。一切都很顺利。他用的是Windows，我用的是Mac。是否有其他人在

TableCellListener

中遇到此问题

代码如下：

package testyo;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.*;
import javax.swing.table.*;
import java.text.*;


public class Testyo {
JFrame mainPanel;
RXTable myTable;
DefaultTableModel myTableModel;

Testyo() {
    mainPanel = new JFrame();
    mainPanel.getContentPane().setLayout(new FlowLayout());
    mainPanel.setSize(1200, 1200);
    mainPanel.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    String[] columnNames = {"ID", "First Name", "Last Name", "Salary"};
    Object[][] data = {
        {1, "aaa", "bbb", 2000}, 
        {2, "ccc", "ddd", 2300},
        {3, "eee", "fff", 1900}
    };
    myTable = new RXTable(new MyTableModel(data, columnNames));
    myTable.setCellSelectionEnabled(true);
    myTable.setSelectAllForEdit(true);
    JScrollPane myScrollPane = new JScrollPane(myTable);
    myTable.setPreferredScrollableViewportSize(new Dimension(1000, 400));
    mainPanel.getContentPane().add(myScrollPane);
    mainPanel.setVisible(true);


    Action action = new AbstractAction () {
        public void actionPerformed(ActionEvent e) {
            TableCellListener tcl = (TableCellListener)e.getSource();
            System.out.println("***");                         
        }
    };
    TableCellListener tcl = new TableCellListener(myTable, action);
}


class MyTableModel extends DefaultTableModel {

    public MyTableModel(Object[][] data, String[] columnNames) {
        super(data, columnNames);
    }

    @Override
    public boolean isCellEditable(int row, int col) {
        return !(col==0);
    }

    @Override
    public Class getColumnClass(int col) {
        if (col == 0 | col == 3)
            return Integer.class;
        else
            return String.class;
    }
}

public static void main(String[] args) {
    // TODO code application logic here
    SwingUtilities.invokeLater(new Runnable() {
       public void run() {
           new Testyo();
       } 
    });
}
}

下面是完整的堆栈跟踪：

TableCellListener不是标准类。我们不知道它是干什么的。您也没有发布异常堆栈跟踪。所以我们完全不知道。我添加了整个错误消息。但是我们仍然不知道关于TableCellListener类的任何信息。我的程序最初添加了一个TableModelListener，我使用了tableChanged方法。但是，即使未在单元格中进行编辑，也会调用此方法。另一方面，TableCellListener仅在实际编辑单元格时调用，它还允许我们访问单元格的新值和旧值。以下链接是我获得该课程的来源：
