I was about to comment that was very
fragile code, and ask..

..did it also work X-plat and X-plaf?

But I thought I'd do a quick test 'here'
before I commented.

<sscce>
import java.awt.*;
import javax.swing.*;
import javax.swing.text.*;

class FileChooserTextField extends JFileChooser {

  FileChooserTextField() {
    super();
    Component theComponent = ((JTextComponent)
      ((Container)((Container)((Container)((Container)
      getComponent(2)).
      getComponent(2))).
      getComponent(2)).
      getComponent(1));
    System.out.println(theComponent);
  }

  public static void main(String[] args) {
    System.out.println("java.version: " +
System.getProperty("java.version") );
    JFileChooser filechooser = new FileChooserTextField();
  }
}
</sscce>

<output>
java.version: 1.6.0
Exception in thread "main"
    java.lang.ArrayIndexOutOfBoundsException:
    No such child: 2
  at java.awt.Container.getComponent(Container.java:281)
  at FileChooserTextField.<init>(FileChooserTextField.java:9)
  at FileChooserTextField.main(FileChooserTextField.java:20)
Press any key to continue . . .
</output>

..so I'll simply ask, on which OS, under
which PLAF, (of Java 1.6) *does* that work?
