java.net socket问题

[qq_26305837]

我编写了一个socket和一个serversocket的交互程序，可是两者之间无法交互，但是调试软件下却正常
求解答，谢谢！

以上为客户端

import java.io.InputStream;

import java.net.Socket;
import java.util.NoSuchElementException;
import java.util.Scanner;

public class App2 implements Runnable{
	ServerSocket ss = null;
	public App2(int port) throws IOException {
		// TODO Auto-generated constructor stub
		System.out.println("Welcome to the terminal server written by Billy Liang!\nListening at the port " + port +"...");
		this.ss = new ServerSocket(port);
		new Thread(this,"main").start();
	}
	
	class Entrance implements Runnable{
		private Socket socket = null;
		private Scanner in = null;
		public Entrance(	Socket arg0, int arg1) {
			this.socket = arg0;
			new Thread(this,"Socket:"+socket.getInetAddress().toString() + ":" + socket.getPort()).start();
			
		}
		public void run(){Scanner in = null;
			// TODO Auto-generated method stub
			try {
				InputStream is = this.socket.getInputStream();
				in = new Scanner(is);
				while(true) {
					String sout = "[" + Thread.currentThread().getName() + "] " + in.nextLine();
					System.out.println(sout);
				}
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}catch (NoSuchElementException e) {
				System.out.println("[" + Thread.currentThread().getName() + "] " + ">>Socket closed by itself");
			}finally {
				in.close();
			}
		}
	}
	
	public static void main(String[] args) throws IOException {
		// TODO Auto-generated method stub
		new App2(1122);
	}

	public void run() {
		// TODO Auto-generated method stub
		int i = 0;
		while(true) {
			try {
				new Entrance(this.ss.accept(), ++i);
				System.out.println(">>new socket accepted:"+ i);
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
	}
}

以上为服务端

[天之上有什么]

两个文件都运行下，不行的话截图控制台信息

[qq_26305837]

我先启动了服务器端

然后启动客户端并且输入了端口号

回车连接上了以后

我在客户端上发信息，但是服务端未反应


可是当我在客户端退出程序时，服务器端却一下子把我刚发的信息全打印了出来，并且显示socket closed


代码我已展出，系统环境时OS X10.13.1，jdk9.0.1，请各位大佬们帮助！非常感谢！

还有就是我拿自己编的程序和已经做好的网络调试工具进行测试却没有问题，就是用自己编的两个进行交互就出现了上述的问题。
