I'm not sure what's happening with your app. I wrote on up to see if it could handle the CTRL-C. Seems to work fine. Do you have any other JMenuItems with the same accelerator?
import java.awt.event.*;
import javax.swing.*;
public class Copy extends JFrame {
     public Copy() {
          this.initMenuBar();
          this.setSize(400, 300);
          this.setVisible(true);
          this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     private void initMenuBar() {
          JMenuBar menubar = new JMenuBar();
          JMenu edit = new JMenu("Edit");
          JMenuItem copy = new JMenuItem(new CopyAction("Copy"));
          edit.setMnemonic(KeyEvent.VK_E);
          copy.setMnemonic(KeyEvent.VK_C);
          copy.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_C, InputEvent.CTRL_MASK));
          edit.add(copy);
          menubar.add(edit);
          this.setJMenuBar(menubar);
     public static void main(String[] args) {
          new Copy();
     private class CopyAction extends AbstractAction {
          public CopyAction(String label) {
               super(label);
          public void actionPerformed(ActionEvent e) {
               System.out.println("Action Performed.");
}
