背景

在IDEA中写了测试代码，但是运行的时候一直提示 java.lang.IllegalStateException: failed to create a child event loop ...

eclipse中同样的代码运行没有问题，于是搜索了一些关于这个错误的解决方法，基本上说是防火墙引起的，需要在防火墙允许应用运行中添加例外应用，添加IDEA即可。

但是，尝试了以后，还是不行......

解决策略

万般无奈之下，萌生了卸载，重新安装的念头，还好坚持了一下，在Stack overflow 找了一下资料。最终，还是找到了解决办法。刚开始直接强制关闭防火墙，此时IDEA可以正常运行程序。既然这样，就可以确定的确是和防火墙有关！但是也不能一直关闭防火墙呀，所以，还是只能添加IDEA防火墙例外应用。

之前添加例外应用时，位置我指定的是IDEA的安装目录bin中的idea.exe，不起作用。位置指定到开始菜单应用程序IDEA，是可以的。具体原因不知道了......
