Code Analysis
if (!NamingProxy.getServers().contains(server.ip)) {
throw new IllegalArgumentException("ip: " + server.ip + " is not in serverlist");
}Part of the code fragment, The value in NamingProxy.getServers() was a collection of hostname: port, but the value in server.ip was ip: port, so it is always possible to fail anyway
