      A DESCRIPTION OF THE PROBLEM :
      In a JApplet the JTextField does not generate the keyReleased event.

      I have reproduced this bug both Opera and Firefox.
      In Safari everyhing seems to be ok.

      REGRESSION. Last worked in version 6u31

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Run the applet in either Firefox or Opera
      2. Press a key in the JTextField

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      keyTyped
      keyPressed
      keyReleased missing!
      ACTUAL -
      keyTyped
      keyPressed

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      import java.awt.event.KeyEvent;
      import java.awt.event.KeyListener;

      import javax.swing.JApplet;
      import javax.swing.JTextField;

      public class keyReleasedDemoApplet extends JApplet {

      public void init() {
      JTextField textfield = new JTextField();
      getContentPane().add(textfield);
      textfield.addKeyListener(new KeyListener() {

      @Override
      public void keyTyped(KeyEvent arg0) {
      System.out.println( " keyTyped " );
      }

      @Override
      public void keyPressed(KeyEvent arg0) {
      System.out.println( " keyPressed " );
      }

      @Override
      public void keyReleased(KeyEvent arg0) {
      System.out.println( " keyReleased missing! " );
      }
      });

      }
      }

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

      CUSTOMER SUBMITTED WORKAROUND :
      If you press multiple keys you MAY get the keyReleased event.
