Gate isn't closed if localhost is used

[TheAIBot]

As the title says, the gate isn't closed if localhost is used as the ip address. Here is a minimal example.

import java.io.IOException;
import java.net.UnknownHostException;

import org.jspace.ActualField;
import org.jspace.RemoteSpace;
import org.jspace.SequentialSpace;
import org.jspace.SpaceRepository;

public class TestStarter {
	public static void main(String[] args) throws UnknownHostException, IOException, InterruptedException {
		try {
			final SpaceRepository rep = new SpaceRepository();
			rep.addGate("tcp://localhost:1290/?conn");
			final SequentialSpace getSpace = new SequentialSpace();
			rep.add("teeest", getSpace);
			final RemoteSpace putSpace = new RemoteSpace("tcp://localhost:1290/teeest?conn");
			
			//close the gate
			rep.closeGate("tcp://localhost:1290/?conn");
			System.out.println("Gate closed");
			
			//now putting something shouldn't work
			putSpace.put("cake");
			System.out.println("Give cake");
			
			//and get also shouldn't work
			getSpace.get(new ActualField("cake"));
			System.out.println("Got cake!");
		} catch (Exception e) {
			e.printStackTrace();
		}		
	}
}

The output is:

Gate closed
Give cake
Got cake!

I would expect both the put and get to throw an error because the connection should have ended.

I should mention that this doesn't only happen with localhost but we have also experienced it with other ip addresses although i am not able to produce an example of it.
Maybe that requires the SpaceRepository and RemoteSpace to be on separate computers to reproduce?
