Problem z odpaleniem clienta

Tworzysz launcher posiadając jakieś tam małe umiejętności... 

Tak się nie sprawdza Stringów:

if(nickInput.getText() != "")

tylko:

if(nickInput.equals(""))

Czemu wszystko robisz statycznie? Zrób jakiś obiekt, a w innych klasach instancje i w nim przetrzymuj, np. nickgracza, uruchamianie Launchera - chodzi o klase Legendary.

Witam, tworzę launcher dla serwera używając mcp.

Kod z launchera - przycisk wykonujący akcję:
 

public void actionPerformed(ActionEvent e) {
		if (e.getSource() == play) {
			if (nickInput.getText() != "") {
				Legendary.nickname = nickInput.getText();
				Legendary.StartClient();
				Start.main(null);
			}
		}
	}

String nicku z klasy Legendary:
 

	public static String nickname;

Główna klasa odpalająca launcher:
 

public class Launcher {

	public static void main(String args[]) {
		Main m = new Main();
		m.setVisible(true);
	}
}

No i klasa Start uruchamiająca okno minecrafta:
 

public class Start
{
    public static void main(String[] args)
    {
        Main.main(concat(new String[] {"--version", "mcp", "--accessToken", "0", "--assetsDir", "assets", "--assetIndex", "1.8", "--userProperties", "{}"}, args));
    }

    public static <T> T[] concat(T[] first, T[] second)
    {
        T[] result = Arrays.copyOf(first, first.length + second.length);
        System.arraycopy(second, 0, result, first.length, second.length);
        return result;
    }
}

void StartClient():
 

public static void StartClient()
	{
		Display.setTitle(Client_Name + " " + "V" + Client_Version + " " + Client_Status);
	}

Oczywiście gdy ustawię manualnie string nickname w klasie Legendary (kod poniżej) i uruchomię bezpośrednio klasę Start, minecraft się odpala, lecz gdy go uruchomię poprzez klasę Launcher, odpala się launcher, wpisuje nick i wywala właśnie tego errora powyżej.
Kod ustawionego stringu nickname:
 

public static String nickname = "Oedeopol";

Proszę o pomoc

wywala nulla bo dajesz nulla w parametrach = (
 

				Start.main(null);
