> in the *ClientCnxn*, we had hard-code cxid which is not elegant.

> if (replyHdr.getXid() == -2) {
> // -2 is the xid for pings
> if (LOG.isDebugEnabled()) {
> LOG.debug("Got ping response for sessionid: 0x"

> + " after "
> + ((System.nanoTime() - lastPingSentNs) / 1000000)
> + "ms");
> }
> return;
> }
> if (replyHdr.getXid() == -4) {
> // -4 is the xid for AuthPacket
> if (replyHdr.getErr() == KeeperException.Code.AUTHFAILED.intValue()) {
> state = States.AUTH_FAILED;
> eventThread.queueEvent(new WatchedEvent(Watcher.Event.EventType.None,
> Watcher.Event.KeeperState.AuthFailed, null));
> eventThread.queueEventOfDeath();
