Arraylist stays empty after putting String inside.

Hello, I am making a PermissionsSystem based on "PermissionsEx". I want to make a Command ("/rang <Player> <Rank>") to set a Players rank, but I dont want other admins to give away ranks. But I dont want to just have a Permission for the command, instead I want to have a Password.

Now here's the Problem: Validating the Password should work (it's encrypted), but I tried making a System that takes a Validation-ID (just a random generated string that Points to a command in a hashmap).

Here's some of my Code I used:

Code:

if(commandSender.hasPermission("pperms.rang")) {

            if(args.length == 1) {
                PermissionUser target = PermissionsEx.getUser(args[0]);
                commandSender.sendMessage(PPerms.prefix + "The Player " + target.getName() + " has the Rank §a" + target.getRankLadderGroup("Plerax").getName());

            } else if(args.length == 2) {
                PermissionUser target = PermissionsEx.getUser(args[0]);
                if(args[1].equalsIgnoreCase("Admin")) {
                    String uid = UUID.randomUUID().toString().replaceAll("-", "").substring(0, 15);
                    new CommandVerifier(uid, target.getName() + " ADMIN LIFETIME");
                    commandSender.sendMessage(PPerms.prefix + "Nutze /validate " + uid + " <Passwort>");
                }

So, a CommandVerifier gets created, thats this class:

Code:

private HashMap < String, String > validationCodes = new HashMap < > ();
public CommandVerifier(String validationCode, String command) {
  validationCodes.put(validationCode, command);
  Bukkit.broadcastMessage("put " + validationCode + " for " + command);
}

@Override
public boolean onCommand(CommandSender commandSender, Command command, String label, String[] args) {
  if (commandSender.hasPermission("pperms.validate")) {
      if (args.length == 0) {
          Bukkit.broadcastMessage("Found those codes:");
          validationCodes.keySet().forEach(Bukkit::broadcastMessage);
      }
  
if (args.length != 2) {
      commandSender.sendMessage(PPerms.prefix + "Please use §c/validate <Code> <Password>");
      return true;
  }

if (validationCodes.containsKey(args[0])) {
      byte[] enteredHashed;
      try {
          MessageDigest digest = MessageDigest.getInstance("SHA-256");
          enteredHashed = digest.digest(args[1].getBytes(StandardCharsets.UTF_8));
          if (enteredHashed == pw) {
              Bukkit.broadcastMessage("Right Password");
          } else {
              Bukkit.broadcastMessage("Wrong Password");
          }
      } catch (NoSuchAlgorithmException e) {
              e.printStackTrace();
      }
  } else {
      Bukkit.broadcastMessage(args[0] + " is not in!");
      commandSender.sendMessage(PPerms.prefix + "Wrong validationcode!");
  }
      return true;
}
  return false;
}

The Array somehow (results of debug) IS EMPTY after it SHOULD have been put in.

Please help, Thanks!
