Keystroke not catching LEFT/RIGHT but able to catch UP/DOWN and all other keys
<p>I'm binding keys to events in my Java app, however, I have encountered a really strange bug that I hope you guys can help me solve.</p>

<pre><code>        KeyStroke up = KeyStroke.getKeyStroke("W");
     KeyStroke down = KeyStroke.getKeyStroke("S");
     KeyStroke right = KeyStroke.getKeyStroke("D");
     KeyStroke left = KeyStroke.getKeyStroke("A");
     KeyStroke p2_up = KeyStroke.getKeyStroke("UP");
     KeyStroke p2_down = KeyStroke.getKeyStroke("DOWN");
     KeyStroke p2_left = KeyStroke.getKeyStroke("LEFT");
     KeyStroke p2_right = KeyStroke.getKeyStroke("RIGHT");
     /*KeyStroke key_1 = KeyStroke.getKeyStroke("1");
     KeyStroke key_2 = KeyStroke.getKeyStroke("2");
     KeyStroke key_3 = KeyStroke.getKeyStroke("3");
     KeyStroke key_4 = KeyStroke.getKeyStroke("4");
     KeyStroke key_5 = KeyStroke.getKeyStroke("5");
     KeyStroke key_6 = KeyStroke.getKeyStroke("6");
     KeyStroke key_7 = KeyStroke.getKeyStroke("7");
     KeyStroke key_8 = KeyStroke.getKeyStroke("8");
     KeyStroke key_9 = KeyStroke.getKeyStroke("9");
     KeyStroke key2_1 = KeyStroke.getKeyStroke("F1");
     KeyStroke key2_2 = KeyStroke.getKeyStroke("F2");
     KeyStroke key2_3 = KeyStroke.getKeyStroke("F3");
     KeyStroke key2_4 = KeyStroke.getKeyStroke("F4");
     KeyStroke key2_5 = KeyStroke.getKeyStroke("F5");
     KeyStroke key2_6 = KeyStroke.getKeyStroke("F6");
     KeyStroke key2_7 = KeyStroke.getKeyStroke("F7");
     KeyStroke key2_8 = KeyStroke.getKeyStroke("F8");
     KeyStroke key2_9 = KeyStroke.getKeyStroke("F9");*/

     InputMap inputMap = content
       .getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);

     inputMap.put(up, "up");
     inputMap.put(down, "down");
     inputMap.put(right, "right");
     inputMap.put(left, "left");

     inputMap.put(p2_up, "up2");
     inputMap.put(p2_down, "down2");
     inputMap.put(p2_right, "right2");
     inputMap.put(p2_left, "left2");

     Bindings KbBinds = new Bindings(this.currentBigBox);

     content.getActionMap().put("up", KbBinds.moveUp);
     content.getActionMap().put("down", KbBinds.moveDown);
     content.getActionMap().put("right", KbBinds.moveRight);
     content.getActionMap().put("left", KbBinds.moveLeft);

        content.getActionMap().put("up2", KbBinds.p2MoveUp);
     content.getActionMap().put("down2", KbBinds.p2MoveDown);
     content.getActionMap().put("right2", KbBinds.p2MoveRight);
     content.getActionMap().put("left2", KbBinds.p2MoveLeft);
</code></pre>

<p>Basically all keys except LEFT/RIGHT are caught and binded. If I replace this</p>

<pre><code>     KeyStroke p2_left = KeyStroke.getKeyStroke("LEFT");
</code></pre>

<p>with 
         KeyStroke p2_left = KeyStroke.getKeyStroke("UP");</p>

<p>while commenting out p2_up, p2_left works as expected.</p>

<p>Any clue?</p>
