KeyListenerクラスへのクラスの追加org.eclipse.swt.widgets.Text。を入力する'a'と、複数のkeyEventsを取得します。私は1つのkeyEventだけを期待しています。何故ですか。

text.addKeyListener(new KeyAdapter() {
    @Override
    public void keyReleased(KeyEvent keyEvent) {
        super.keyReleased(keyEvent);
        logger.log(Level.INFO, "keyEvent-->" + "\n" +  
                            "character :" + keyEvent.character + "\n" + 
                            "code      :" + keyEvent.keyCode + "\n" +
                            "location  :" + keyEvent.keyLocation + "\n" +
                            "stateMask :" + keyEvent.stateMask + "\n" +
                            "time      :" + keyEvent.time + "\n" +
                            "hashCode  :" + keyEvent.hashCode() + "\n" +
                            "data      :" + keyEvent.data + "\n" +
                            "doit      :" + keyEvent.doit + "\n");
    }
});

出力（キーボードの「a」を1回押した後）：

そのコンポーネントの存続期間中に複数のKeyAdapterを追加した可能性があります。何getKeyListeners().lengthが返されるかを確認して、確認してください。
