CUSTOMER SUBMITTED WORKAROUND :
None known
In some situation JTextField doesn't show cursor and shows cutted text. I tested this under jdk 5, 6 and 7 and I got the same results.

Below is a test (to see problem press 'end' and then 'home'):

----------------------------------------------------------
import javax.swing.*;

import com.sun.java.swing.plaf.windows.WindowsLookAndFeel;

public class TextFieldProblem {
    private static final String TEXT = "ar_securities_by_issuer_r-2006-12-13-09-55-47-25321.xls";

    public static void main(String[] args) throws Exception {
        UIManager.setLookAndFeel(new WindowsLookAndFeel());

        JFrame frame = new JFrame();

        JTextField field = new JTextField(TEXT);

        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        frame.getContentPane().add(field);
        frame.pack();
        frame.setSize(frame.getWidth() - 2, frame.getHeight());
        frame.setLocationRelativeTo(null);

        frame.setVisible(true);
    }
}
