Steps to reproduce:
1. Compile DialogTest.java
     javac DialogTest.java
2. Run after setting the classpath
     java DialogTest
3. Press "Open a File" button to bring up the JFileChooser. Choose a directory which has a lot of sub directories and files
4. Press a letter on the keyboard which is not visible on the JFileChooser to select a directory. For eg: there is a directory by name "pass" which is not visible initially on the JFileChooser. Now if you press P, this directory gets selected but the JFileChooser does not scroll to show us the selection but if you scroll manually (by pressing the scroll bar) you will notice that the directory is selected.

public class DialogTest extends JFrame {

    public DialogTest() {
        super("FileChooserDemo");

        //Create the log first, because the action listeners
        //need to refer to it.

        //Create a file chooser
        final JFileChooser fc = new JFileChooser();
        fc.setMultiSelectionEnabled(true);
        TextFilter txt = new TextFilter();
        fc.setFileFilter(txt);
        fc.addChoosableFileFilter(txt);

        //Create the open button
        JButton openButton = new JButton("Open a File...");
        openButton.setMnemonic(openButton.getText().charAt(0));
        openButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                int returnVal = fc.showOpenDialog(DialogTest.this);

                if (returnVal == JFileChooser.APPROVE_OPTION) {
                    File file = fc.getSelectedFile();

        //For layout purposes, put the buttons in a separate panel
        JPanel buttonPanel = new JPanel(new FlowLayout());
        buttonPanel.add(openButton);

        //Add the buttons and the log to the frame
        Container contentPane = getContentPane();

        frame.addWindowListener(new WindowAdapter() {

                System.exit(0);
            }

        });

        frame.pack();
        frame.setVisible(true);
    }

        public boolean accept(File f)
        {
                if ( f.isDirectory() || f.getName().endsWith("txt") || f.getName

                        return true;
                else
                        return false;
        }

        public String getDescription()
