【DM版本】: v8.1.4.6
【操作系统】：macOS Tahoe26.4.1
【CPU】: Intel
【问题描述】*：
相同代码在 Windows 电脑上就没问题，但是在 mac 上就会报错，不能建立连接，尝试过增加以下参数，也尝试过更换驱动 jar 版本，均无效，但是在 mac 上通过SQLark百灵就能连接，请大佬们帮忙看下，感激不尽。

java.net.preferIPv4Stack
java.net.preferIPv6Stack
java.net.preferIPv4Addresses
java.net.preferIPv6Addresses

代码如下

import java.sql.Connection;
import java.sql.DriverManager;

public class SimpleTest {

    public static void main(String[] args) throws Exception {
        Class.forName("dm.jdbc.driver.DmDriver");
        Connection conn = DriverManager.getConnection("jdbc:dm://xxx.xxx.xxx.xxx:5236", "user", "password");
        System.out.println("连接成功");
        conn.close();
    }

}

异常堆栈如下
