It occurs during the execution of following program:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class TenButtons extends JFrame{

    JButton [] btns= new JButton[10];

    public static void main(String args[]){
        new TenButtons();
    }
    public TenButtons(){
        this.setSize(500,500);
        this.setTitle("10 Buttons");
        this.setLayout(new GridLayout(5,2));
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        for(int i=0; i<btns.length; i++){
           btns[i]=new JButton("Button ");
           this.add(btns[i]);
        }
        this.setVisible(true);
    }
}

My JDK_HOME/jre/lib/accessibility.properties file has the following content:
