Buggy source:

    stockRound.done(gameStatus.getSRPlayer());

  }
  try {

Fixed version (ground truth):
public void actionPerformed(ActionEvent actor){
  int returnVal=0;
  player=GameManager.getCurrentPlayer();
  if (actor.getActionCommand().equalsIgnoreCase("String_Node_Str")) {
    buyButtonClicked();
    passButton.setText("String_Node_Str");
    passButton.setMnemonic(KeyEvent.VK_D);
  }
 else   if (actor.getActionCommand().equalsIgnoreCase("String_Node_Str")) {
    sellButtonClicked();
    passButton.setText("String_Node_Str");
    passButton.setMnemonic(KeyEvent.VK_D);
  }
 else   if (actor.getActionCommand().equalsIgnoreCase("String_Node_Str")) {
    stockRound.done(gameStatus.getSRPlayer());
    passButton.setText("String_Node_Str");
    passButton.setMnemonic(KeyEvent.VK_P);
  }
  try {
    JMenuItem menuItem=(JMenuItem)actor.getSource();
    if (menuItem.getText().equalsIgnoreCase("String_Node_Str"))     System.exit(0);
    if (menuItem.getText().equalsIgnoreCase("String_Node_Str"))     returnVal=new JFileChooser().showSaveDialog(this);
    if (menuItem.getText().equalsIgnoreCase("String_Node_Str") && menuItem.isSelected())     GameUILoader.messageWindow.setVisible(true);
