Buggy source:
void initPlayersPane(GameInfo selectedGame){
  playersPane.setVisible(false);
  List<String> prefilledPlayers=Lists.newArrayList();
  for (  PlayerInfo player : players) {
    if (player.name != null && player.name.getText().length() > 0) {
      prefilledPlayers.add(player.name.getText());
    }
  }
  players.clear();
  if (prefilledPlayers.isEmpty()) {
    prefilledPlayers=Arrays.asList(Config.get("String_Node_Str").split("String_Node_Str"));
  }
  playersPane.removeAll();
  int maxPlayers=selectedGame.getMaxPlayers();
  int minPlayers=selectedGame.getMinPlayers();
  playersPane.setLayout(new GridLayout(maxPlayers + 1,0,0,2));
  playersPane.setBorder(BorderFactory.createLoweredBevelBorder());
  playersPane.add(new JLabel("String_Node_Str"));
  playersPane.add(randomizeButton);
  for (int i=0; i < maxPlayers; i++) {
    PlayerInfo player=new PlayerInfo();
    player.number.setText(LocalText.getText("String_Node_Str",Integer.toString(i + 1)));
    player.name.setInputVerifier(controller.playerNameVerifier);
    if (i < prefilledPlayers.size()) {
      player.name.setText(prefilledPlayers.get(i));
    }
    if (i < minPlayers) {
      player.name.setBorder(BorderFactory.createLineBorder(Color.RED));
    }
    if (i <= minPlayers || i <= prefilledPlayers.size()) {
      player.name.setEnabled(true);
      player.number.setForeground(Color.BLACK);
    }
 else {
      player.name.setEnabled(false);
      player.number.setForeground(Color.GRAY);
    }
    playersPane.add(player.number);
    playersPane.add(player.name);

}

Fixed version (ground truth):
void initPlayersPane(GameInfo selectedGame){
  playersPane.setVisible(false);
  List<String> prefilledPlayers=Lists.newArrayList();
  for (  PlayerInfo player : players) {
    if (player.name != null && player.name.getText().length() > 0) {
      prefilledPlayers.add(player.name.getText());
    }
  }
  players.clear();
  if (prefilledPlayers.isEmpty()) {
    prefilledPlayers=Arrays.asList(Config.get("String_Node_Str").split("String_Node_Str"));
  }
  playersPane.removeAll();
  int maxPlayers=selectedGame.getMaxPlayers();
  int minPlayers=selectedGame.getMinPlayers();
  playersPane.setLayout(new GridLayout(maxPlayers + 1,0,0,2));
  playersPane.setBorder(BorderFactory.createLoweredBevelBorder());
  playersPane.add(new JLabel("String_Node_Str"));
  playersPane.add(randomizeButton);
  for (int i=0; i < maxPlayers; i++) {
    PlayerInfo player=new PlayerInfo();
    player.number.setText(LocalText.getText("String_Node_Str",Integer.toString(i + 1)));
    player.name.setInputVerifier(controller.playerNameVerifier);
    if (i < prefilledPlayers.size()) {
      player.name.setText(prefilledPlayers.get(i));
    }
    if (i < minPlayers) {
      player.name.setBorder(BorderFactory.createLineBorder(Color.RED));
    }
    if (i < minPlayers || i <= prefilledPlayers.size()) {
      player.name.setEnabled(true);
      player.number.setForeground(Color.BLACK);
    }
 else {
      player.name.setEnabled(false);

    }
    final int playerNr=i;
    player.name.addMouseListener(new MouseAdapter(){
      @Override public void mouseClicked(      MouseEvent e){
        if (playerNr == getPlayerCount()) {
          enablePlayer(playerNr);
          setFocus(playerNr);
        }
