'setAutomaticReconnect' not reconnection, when broker is initially not available

When using `connOpts.setAutomaticReconnect(true)` I was expecting, that the client also remains trying to connect to the broker, when the broker was not available on the first try.
But for me the automatic reconnect just works, when the broker become unavailable during runtime.

Is that intended behavior?

Thanks

I am using: "org.eclipse.paho" % "org.eclipse.paho.client.mqttv3" % "1.2.5",
