FIX: SHIFT+BACKSPACE breaks cursor position in an AWT TextField (260053)

MORE INFORMATION

In an AWT TextField, the SHIFT+BACKSPACE combination is equivalent to the BACKSPACE key. However, when you press SHIFT+BACKSPACE, the cursor moves to the left one character. This does not appear until the user begins to type again.

Steps to Reproduce Behavior

The following Java code demonstrates this problem:

import java.applet.*;
import java.awt.*;
import java.awt.event.*;

public class Test extends Applet {
	public static void main (String argv[] ) {
		new MyFrame();
	}

	public void init() {
		new MyFrame();
	}
}

class MyFrame extends Frame {

	MyFrame () {
		setLayout(new BorderLayout());
		TextField f1 = new TextField("abc");
		add(BorderLayout.NORTH, f1);

		addWindowListener(new CloseAdapter());
		setBounds(100, 100, 200, 200);
		setVisible(true);
	}
}


class CloseAdapter extends WindowAdapter {
	public void windowClosing (WindowEvent e) {
		System.exit(0);
	}
}
				

Compile Test.java and type the following from the command line: In the text box, you can use the arrow keys to move the cursor to the end of the text string. Press SHIFT+BACKSPACE twice. Notice that the cursor does not move and nothing is erased. Now begin typing and notice that the insertion point has moved to the left two characters.
