Method connectionLost from ConnectionObserver Method is called when the node is risen, and not when down.

I use following code:

client.addObserver(new ConnectionObserver() {
@Override
public void connectionEstablished(SocketAddress sa,
int reconnectCount)

@Override
public void connectionLost(SocketAddress sa)

});

I'm studying the following scenario: shutting down node(power off on virtual machine). After that, I power on the machine and waiting for Couchbase node recovery. I see that connectionLost is called only when I power on machine, but not when node is really down.

Interesting, but when I'm run absolutely the same program on Windows 7 connectionLost is called after a few seconds after node is down.
