   相似的问题。
   使用arthas
   // 获取NetUtils 实例hash
   sc -d *NetUtils 
   // 使用ognl调用org.apache.dubbo.common.utils.NetUtils#getValidNetworkInterfaces
   ognl -c 7728643a -x 3 
'@org.apache.dubbo.common.utils.NetUtils@getValidNetworkInterfaces()'
   发现网卡列表里docker0网卡在我们的物理网卡之前
   @LinkedList[
       ....
       @NetworkInterface[
           name=@String[docker0],
           displayName=@String[docker0],
       ],
       @NetworkInterface[
           name=@String[ens192],
           displayName=@String[ens192],
       ],
   ]
   2.7.14之前用的break，这只是中断了while循环。2.7.14我猜测是为了修复这个逻辑bug，结果走到docker0之后就退出了。
