     * (1) MyAsyncHttpClient performs the HTTP post asynchronously
     * (2) OpenHABVoiceService stops because all intents have been handled
     * (3) MyAsyncHttpClient tries to call onSuccess() or onFailure(), which is not possible
     *     anymore because OpenHABVoiceService is already stopped/destroyed.
