hadesvip opened a new issue #9167:
URL: https://github.com/apache/dubbo/issues/9167


   ### Environment
   
   * Dubbo version: 3.0.2.1
   * Operating System version: win10
   * Java version: openjdk 14
   
   ### Steps to reproduce this issue
   
   1. 在openjdk14 版本上运行dubbo时候启动报错，提示如下

   2.  调试源码发现，openjdk14 修改了InetSocketAddress的toString方法，修改源码如下

   3.  
调用InetSocketAddress.toString()获取IP地址的时候导致返回了“127.0.0.1/<unresolved>:2181”，获取IP地址触发了UnknownHostException运行时异常返回了默认的值

   4. 后续对ip地址进行校验的时候，SocketAddress中的addr并没有设置值，直接触发了UnresolvedAddressException异常
