Защо булевата стойност не се превключва?

Първо искам да благодаря за всяка помощ. Аз съм сравнително нов в програмирането на Java. Създадох проста игра TicTacToe и имам малък проблем.

От време на време "X" или "O" ще се играят два пъти подред. Имам булева променлива, която трябва да превключи от true към false, за да промени "X" на "O", когато всеки играч вземе ход, но по някаква причина тя не се превключва на случаен принцип.

Мисля, че може да е проблем с Eclipse или нещо подобно, защото не разбирам защо иначе би направил това.

По-долу е кодът за играта:

public class gameMain {

    Boolean player = true;
    JPanel gameBoard;
    JButton[] b = new JButton[10];
    Font font = new Font("Arial", Font.BOLD, 99);
    ListenForButtons lfb = new ListenForButtons();

    public static void main(String args[]) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                new gameMain();
            }
        });
    }

    public gameMain() {
        JFrame j = new JFrame("TicTacToe");
        j.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        j.setLocationRelativeTo(null);
        j.setSize(400, 400);

        gameBoard = new JPanel();
        gameBoard.setLayout(new GridLayout(3, 3));
