Java永无止境的切换循环(有时)eclipse

Question

我对这个完全不解，我在循环中有一个 switch 语句:

package com.example.project

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class Keyserver {
static ServerSocket server;
static Socket soc;
static ObjectInputStream in;
static int key;
static Robot bot;
static boolean shift = false;

public static void main(String[] args) throws AWTException{
    bot = new Robot();
    while(true){
        try {
            server = new ServerSocket(4321, 10);
            soc = server.accept();
            System.out.println("Accepted port");
            in = new ObjectInputStream(soc.getInputStream());
        } catch (IOException e) {
            e.printStackTrace();
        }
        while(soc.isConnected()){
            try {
                key = in.readInt();
                System.out.println(key);
                switch(key){
                case(7):
                    bot.keyPress(KeyEvent.VK_0);
                    bot.keyRelease(KeyEvent.VK_0);
                    break;
                case(8):
                    bot.keyPress(KeyEvent.VK_1);
                    bot.keyRelease(KeyEvent.VK_1);
                    break;
                case(9):
                    bot.keyPress(KeyEvent.VK_2);
                    bot.keyRelease(KeyEvent.VK_2);
                    break;
                case(10):
                    bot.keyPress(KeyEvent.VK_3);
                    bot.keyRelease(KeyEvent.VK_3);
                    break;
                                    ....
                case(53):
                    bot.keyPress(KeyEvent.VK_Y);
                    bot.keyRelease(KeyEvent.VK_Y);
                    break;
                case(54):
                    bot.keyPress(KeyEvent.VK_Z);
                    bot.keyRelease(KeyEvent.VK_Z);
                    break;
                case(4):
                    bot.keyPress(KeyEvent.VK_BACK_SPACE);
                    bot.keyRelease(KeyEvent.VK_BACK_SPACE);
                    break;
                case(62):
                    bot.keyPress(KeyEvent.VK_SPACE);
                    bot.keyRelease(KeyEvent.VK_SPACE);
                    break;
                case(59):
                    if(!shift){
                        bot.keyPress(KeyEvent.VK_SHIFT);
                    }else{
                        bot.keyRelease(KeyEvent.VK_SHIFT);
                    }
                    shift = !shift;
                    break;
                case(60):
                    if(!shift){
                        bot.keyPress(KeyEvent.VK_SHIFT);
                    }else{
                        bot.keyRelease(KeyEvent.VK_SHIFT);
                    }
                    shift = !shift;
                    break;

                case(90):
                    bot.keyPress(KeyEvent.VK_1);
                    bot.keyRelease(KeyEvent.VK_1);
                    break;
                case(91):
                    bot.keyPress(KeyEvent.VK_2);
                    bot.keyRelease(KeyEvent.VK_2);
                    break;
                case(92):
                    bot.keyPress(KeyEvent.VK_0);
                    bot.keyRelease(KeyEvent.VK_0);
                    break;
                case(93):
                    bot.keyPress(KeyEvent.VK_3);
                    bot.keyRelease(KeyEvent.VK_3);
                    break;
                case(104):
                    bot.keyPress(KeyEvent.VK_ENTER);
                    bot.keyRelease(KeyEvent.VK_ENTER);
                    break;
                case(105):
                    bot.keyPress(KeyEvent.VK_BACK_SPACE);
                    bot.keyRelease(KeyEvent.VK_BACK_SPACE);
                    break;
                case(106):
                    bot.keyPress(KeyEvent.VK_MINUS);
                    bot.keyRelease(KeyEvent.VK_MINUS);
                    break;
                case(107):
                    bot.keyPress(KeyEvent.VK_EQUALS);
                    bot.keyRelease(KeyEvent.VK_EQUALS);
                    break;
                case(108):
                    bot.keyPress(KeyEvent.VK_TAB);
                    bot.keyRelease(KeyEvent.VK_TAB);
                    break;
                case(109):
                    bot.keyPress(KeyEvent.VK_ESCAPE);
                    bot.keyRelease(KeyEvent.VK_ESCAPE);
                    break;
            }

            } catch (IOException e) {
                try {
                    e.toString();
                    in.close();
                    soc.close();
                    server.close();
                    break;
                } catch (IOException e1) {
                    e1.toString();
                }   
            }
        }
        System.out.println("PORT CLOSED");
    }

}

}

除 90-93 外一切正常，它们导致程序永远循环，直到我单击 eclipse 然后它停止。这不是 eclipse 问题，因为当我将它构建到 .jar 中时，我得到了相同的结果并且它不是服务器问题，因为当我制作发送 90 发送 7 的按钮时它工作正常

似乎只有 90-93 会导致无限循环，我已经尝试将数字从 90 更改为 200 之类的值，但没有成功

有什么启发吗？

听起来像这样的代码:

bot.keyPress(KeyEvent.VK_1);
bot.keyRelease(KeyEvent.VK_1);

由于某种原因挂起。与 switch 语句无关。
