Binding default action of JTextComponent with JDK1.2 & 1.3

Question

Hello,
I have a specific text component who extends JTextField. This component must work on JDK1.3 & 1.2.
I catch certain key events in the method processComponentKeyEvent to have the control over my component (in particular VK_BACK_SPACE, VK_LEFT and VK_RIGHT) and I don't want the default action inherit from JTextComponent to be exectued. With JDK1.2 this problem doesn't appear because I think the event is consume when it is thread by the processComponentKeyEvent and the operation of searching in the default key actions is not executed. But, with JDK1.3 they change the model of mapping key to event and the default actions are executed although the event is passing by the processComponentKeyEvent and e.consume was call. I find something who work on JDK1.3 by binding the default actions of key events with a "null" action. I do something like :
myField.getInputMap().put(myKeyStroke, "none");
My problem is that my components must work both with JDK1.3 & 1.2 without having two different versions of the component but the solution doesn't compile because getInputMap(KeyStroke, objectKeyToAction) doesn't exist on JDK1.2.
I try to removeActionFromKeyStroke method but it doesn't work and in plus, the change going to apply to all text component in the application.
There is a solution who can compile on both JDK1.3 & 1.2 ?
Is it a good idee to use reflection to test the presence of the method and apply the correction or you have a better idee.
Tanks a lot

Try using a KeyListener instead. It allows you to consume the KeyEvent, at least it does on JDK1.3.
keyListener = new KeyAdapter()
     public void keyPressed(KeyEvent e)
          switch (e.getKeyCode())
               case KeyEvent.VK_RIGHT:
                    e.consume();
                    // add your code here
                    break;
               case KeyEvent.VK_LEFT:
                    e.consume();
                    // add your code here
                    break;
};
