Buggy source:

    Canary.warps().addWarp(newWarp);
    player.sendMessage(Colors.YELLOW + Translator.translateAndFormat("String_Node_Str",args[1]));
    return;

Fixed version (ground truth):
private void player(Player player,String[] args){
  Warp test=Canary.warps().getWarp(args[1]);
  if (test != null) {
    if (test.isPlayerHome() || !player.hasPermission("String_Node_Str")) {
      player.notice(Translator.translate("String_Node_Str"));
      return;
    }
  }
  if (args.length == 2 && player.hasPermission("String_Node_Str")) {
    Warp newWarp=new Warp(player.getLocation(),args[1]);
    Canary.warps().addWarp(newWarp);
    player.sendMessage(Colors.YELLOW + Translator.translateAndFormat("String_Node_Str",args[1]));
    return;
  }
 else   if (args.length > 3) {
    if (args[2].equalsIgnoreCase("String_Node_Str") && player.hasPermission("String_Node_Str")) {
      Group[] groups=new Group[args.length - 3];
      for (int i=0; i < groups.length; i++) {
        groups[i]=Canary.usersAndGroups().getGroup(args[i + 3]);
      }
      Warp newWarp=new Warp(player.getLocation(),groups,args[1]);
      Canary.warps().addWarp(newWarp);
      player.sendMessage(Colors.YELLOW + Translator.translateAndFormat("String_Node_Str",args[1]));
      return;
    }
