我也是这样的错误，解决方法就是更换系统环境变量配置中jdk版本，我下载的es版本是7.16.2，系统中的jdk版本是18，更换成jdk17后，错误解决了,查找es对应的jdk版本可以看这里：https://github.com/elastic/elasticsearch/issues/85665%EF%BC%9B%E5%A6%82%E4%BD%95%E6%9B%B4%E6%8D%A2jdk%E7%89%88%E6%9C%AC%E5%8F%AF%E4%BB%A5%E5%9C%A8%E7%BD%91%E4%B8%8A%E6%90%9C%E4%B8%80%E4%B8%8B%EF%BC%8C%E8%BF%99%E4%B8%AA%E8%A7%A3%E5%86%B3%E6%96%B9%E6%A1%88%E5%BE%88%E5%9B%BA%E5%AE%9A
