JTextPane won't wrap

I'm trying to get JTextPane to word-wrap. I've searched this site and across the Internet and it seems that JTextPane is supposed to word-wrap by default- most trouble people have is with disabling the wrap or getting the wrap to work inside a JScrollPane. I've tried various combinations of TextPanes, ScrollPanes and JPanels, to no avail. Below is the simplest possible code tested that still has the problem (no wrap).

public class Looseleaf extends JFrame{

    public Looseleaf(){
        this.setSize(200,200);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
        JTextPane txtPane = new JTextPane();
        this.add(txtPane);
        this.setVisible(true);
    }
}

I've used JTextArea instead of JTextPane

then used method:

textArea.setLineWrap(true);

At least in my case, the following coding works. If you add the JTextPane into a JPane with border layout and add that pane into the JScrollPane, then the lines would not wrap.

Depending on you layout, JTextPane may or may not wrapped, based on what it perceves as it's available size.

Instead, add the JTextPane to a JScrollPane instead...

public class Looseleaf extends JFrame{
    public Looseleaf(){
        this.setSize(200,200);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
        JTextPane txtPane = new JTextPane();
        this.add(new JScrollPane(txtPane)); // <-- Add the text pane to a scroll pane....
        this.setVisible(true);
    }
}

Updated with additional example

Try this instead. This worked for me.

public class TestTextPaneWrap {

    public static void main(String[] args) {
        new TestTextPaneWrap();
    }

    public TestTextPaneWrap() {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (Exception ex) {
                }

                JFrame frame = new JFrame("Test");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.add(new TestPane());
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);

            }
        });
    }

    public class TestPane extends JPanel {

        public TestPane() {
            setLayout(new BorderLayout());
            JTextPane editor = new JTextPane();
            editor.setMinimumSize(new Dimension(0, 0));
            add(new JScrollPane(editor));
        }

    }
}
