    Question Java Socket not allowing swing frame to show up

    Hey all I am at a loss as to why its doing this. If I just run the server and standalone client it works just fine. However, once I use my code for the client it seems to get stuck...
    static JTextField textField         = null;
    static JTextArea messageArea        = null;
    static String serverAddress         = "localhost";
    static UFTtrack window              = null;
     
    public static JFrame frame;
    public ImageIcon[] images;
    static JTable table;
    Date lastUpdate;
    static Timer timer;
    static Scanner in;
    static PrintWriter out;
     
    public static void main(String[] args) {
            EventQueue.invokeLater(new Runnable() {
                @SuppressWarnings({ "static-access" })
                public void run() {
                    try {
                        UIManager.setLookAndFeel(new MaterialLookAndFeel());
                    } catch (UnsupportedLookAndFeelException e1) {
                        e1.printStackTrace();
                    }
     
                    try {
                        window = new UFTtrack();
     
                        placeChatOnScreen();
                        createTable();
                        SystemTrayz.createTray();
     
                        centreWindow(frame);
                        window.frame.setVisible(true);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            });
        }
     
    public UFTtrack() {
       initialize();
    }
     
    private void initialize() {
            frame = new JFrame("UFTtrack");
            frame.setTitle("UFT Tracker");
            frame.setResizable(false);
            frame.setLocationByPlatform(true);
            frame.setSize(1308, 900);
            frame.setBounds(100, 100, 450, 300);
            frame.setMinimumSize(new Dimension(1308, 900));
            frame.setPreferredSize(new Dimension(1308, 900));
            frame.setLayout(null);
            frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
        }
     
    @SuppressWarnings({ "resource", "unused" })
    private static void placeChatOnScreen() {
        try {                       
            textField = new JTextField();
            textField.setFont(new Font("Segoe UI", Font.PLAIN, 13));
            textField.setDragEnabled(true);
            textField.setBorder(new MatteBorder(1, 1, 1, 1, (Color) new Color(0, 0, 0)));
            textField.setBounds(338, 838, 954, 22);
            frame.getContentPane().add(textField);
     
            messageArea = new JTextArea();
            messageArea.setEditable(false);
            messageArea.setFont(new Font("Segoe UI", Font.PLAIN, 13));
            messageArea.setBorder(new MatteBorder(1, 1, 1, 1, (Color) new Color(0, 0, 0)));
            messageArea.setDragEnabled(true);
            messageArea.setName("chatArea");
            messageArea.setWrapStyleWord(true);
            messageArea.setBounds(338, 648, 954, 181);
            frame.getContentPane().add(messageArea);
     
            textField.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    out.println(textField.getText());
                    textField.setText("");
                }
            });
     
            Socket socket = new Socket("localhost", 8877);
     
            in = new Scanner(socket.getInputStream());
            out = new PrintWriter(socket.getOutputStream(), true);
     
            while (in.hasNextLine()) {
                String line = in.nextLine();
     
                if (line.startsWith("SUBMITNAME")) {
                    out.println(getName());
                } else if (line.startsWith("NAMEACCEPTED")) {
                    textField.setEditable(true);
                } else if (line.startsWith("MESSAGE")) {
                    messageArea.append(line.substring(8) + "\n");
                }
            }
        } catch (IOException e1) {
            e1.printStackTrace();
        }
    }
    It does fine until it gets to the "NAMEACCEPTED" else if condition and it just steps out of the while loop and then nothing happens. No error of any kind. It just doesn't how the swing frame!
    If I comment out:
    /*while (in.hasNextLine()) {
        String line = in.nextLine();
     
        if (line.startsWith("SUBMITNAME")) {
            out.println(getName());
        } else if (line.startsWith("NAMEACCEPTED")) {
            textField.setEditable(true);
        } else if (line.startsWith("MESSAGE")) {
            messageArea.append(line.substring(8) + "\n");
        }
    }*/
    and run it the swing frame loads up just fine. But my Socket (which I am wanting in my swing app) keeps it for some reason passing.
    window = new UFTtrack();
     
    placeChatOnScreen();
    createTable();
    SystemTrayz.createTray();
     
    centreWindow(frame);
    window.frame.setVisible(true);
    To sum all this up - the above code hits the window = new UFTtrack(); and placeChatOnScreen() but after it exits the While loop in the placeChatOnScreen() it never continues to createTable(); What's the deal???
