FULL PRODUCT VERSION :
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)
but running under JRE 1.6.0

ADDITIONAL OS VERSION INFORMATION :
Linux mymachinename 2.6.12-1-k7-smp #1 SMP Tue Aug 9 14:38:47 UTC 2005 i686 GNU/Linux

A DESCRIPTION OF THE PROBLEM :
In previous versions of the JRE and on different platforms, a VK_CANCEL KEY_TYPED KeyEvent is generated when Ctrl+C is typed on a component. However, this does not seem to be the case when running JRE 1.6.0 on Linux.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a new Swing GUI with a JFrame.
2. Attach a KeyListener to the JFrame.
3. Show the JFrame.
4. Put focus in the JFrame.
5. Observe the calls to the KeyListener when typing Ctrl+C.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expect to get KeyEvents where getKeyChar() returns KeyEvent.VK_CANCEL.
ACTUAL -
No VK_CANCEL events are produced.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class CancelTest {

    private void showGUI() {
        JFrame myFrame = new JFrame();
        myFrame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
        myFrame.setLayout(new BorderLayout());
        myFrame.setSize(400,300);
        myFrame.addKeyListener(new CancelKeyListener());
        myFrame.setVisible(true);
    }

    private class CancelKeyListener extends KeyAdapter {
        public void keyTyped(KeyEvent e) {
            System.out.println("keyTyped");
            if (e.getKeyChar() == KeyEvent.VK_CANCEL) {
                System.out.println("keyTyped: VK_CANCEL");
            }
        }

        public void keyPressed(KeyEvent e) {
            System.out.println("keyPressed");
            if (e.getKeyChar() == KeyEvent.VK_CANCEL) {
                System.out.println("keyPressed: VK_CANCEL");
            }
        }
    }

    public static void main(String[] args) {
        final CancelTest myCancelTest = new CancelTest();
        SwingUtilities.invokeLater(new Runnable() {
                public void run() {
                    myCancelTest.showGUI();
                }
            }
            );
    }
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
One workaround is to check for the Ctrl+C manually on Linux. That is, check for VK_CANCEL, but also if running on a Linux machine, check that getKeyChar() returns either 'c' or 'C' and that ((getModifiers() & KeyEvent.CTRL_MASK) != 0).

Release Regression From : 5.0u10
The above release value was the last known release where this
bug was not reproducible. Since then there has been a regression.
