Java – calling a new thread inside is a constructor

Is it correct to create a thread and call its start () method in the constructor of the class?

public class Server implements Runnable {

    private ServerSocket server;

    public Server(int port) {
        try {
            //Opens a new server 
            server = new ServerSocket(port);
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }

        new Thread(this,"Server").start();
    }

    @Override
    public void run() {
    }
}

Solution

With all due respect, don't do that You allow this reference to escape during construction
