    private javax.swing.JTextArea jTextArea1;

    public TabTestJFrame() {
        initComponents();
        jTextArea1.setTabSize(8);
    }

    private void initComponents() {

        jScrollPane1 = new javax.swing.JScrollPane();
        jTextArea1 = new javax.swing.JTextArea();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        jTextArea1.setFont(new java.awt.Font("Monospaced", 0, 10));
        jTextArea1.setLineWrap( true );
        jTextArea1.setText("#################################################\n# Some Text\t\t\t\t\t#\n# Some Other Much Longer Text\t\t\t#\n#################################################");
        jScrollPane1.setViewportView(jTextArea1);

        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(layout.createSequentialGroup()
                .addContainerGap()
                .addComponent(jScrollPane1, javax.swing.GroupLayout.DEFAULT_SIZE, 446, Short.MAX_VALUE)
                .addContainerGap())
        );

            .addGroup(layout.createSequentialGroup()
                .addContainerGap()
                .addComponent(jScrollPane1)

        pack();

    public static void main(String args[]) {
        System.out.println("Java Version: " + System.getProperty("java.specification.version"));
        java.awt.EventQueue.invokeLater(() -> {new TabTestJFrame().setVisible(true);});
