onlineexecutor's Issues

Found a possible security concern

Hello 👋

I run a security community that finds and fixes vulnerabilities in OSS. A researcher (@achiove) has found a potential issue, which I would be eager to share with you.

Could you add a SECURITY.md file with an e-mail address for me to send further details to? GitHub recommends a security policy to ensure issues are responsibly disclosed, and it would help direct researchers in the future.

Looking forward to hearing from you 👍

看完了doc，说说个人看法

我只能写java，java写得也不咋样，编译原理什么都不懂，所有的基础课程也没学过，会的只有CURD。
感觉想法其实挺好的，调用jdk系统类库进行编译，然后hack一部分调用，里面涉及的java知识只是听过却没写过，所以佩服。
不过有个很麻烦的问题，你只hack了System，同时又没有屏蔽太多的功能，那么用户要是不写System.out.println怎么办呢？jdk里功能太多了。用户可以用jdk发起很多系统调用的，比如shell。
那么用户其实完全可以调用shell，然后尝试找到javac，再编译，再执行。
这只是其中的一小部分，还有很多事情可以做。
不过前面有关字节码的知识，有关jdk vm相关类库的知识让我受益良多，所以还是非常感谢。

当用户的Java程序没有输出的时候会发生NullPointerException

当用户的Java程序没有输出的时候会发生NullPointerException，因为ExecuteStringSourceService.java里e.getCause().getMessage()会返回一个null

给执行代码的线程池加个RejectedExecutionHandler

给客户端代码的标准输出内容的多少加一个限制

不能让每个客户端的标准输出内容太多，加一个限制，就像客户端程序的运行时间需要限制一样。

关于selenium源代码运行

selenium 代码运行报错，出现依赖jar缺失，selenium jar包路径放在什么位置，请指教！

README里面的图是用什么画的吗？

讲解图很清晰。想问下是什么软件画的

关于在CentOS下运行报错

在MacOS下运行正常，但是放到CentOS下会报错，尝试了多个JDK版本，应该不是版本问题，感觉是编译上第一步在生成JavaFileManager出现了问题。
