无法启动nacos 2.4.1，可以启动2.4.0

[reigadegr]

use cmdline: bin\startup.cmd -m standalone
启动2.4.0无任何问题，具体请看日志。err.log是启动时重定向出来的信息。

使用 JDK 8 呢？

可以看看这个：#12498

[reigadegr]

通过#12498 这个issue的方法可以正常启动和使用。但是还有错误。

看起来是hessain包冲突了，有自己该过代码吗

我用官网的下载包启动，没有遇到这个问题。

[reigadegr]

没改过他的代码，我也不会。你用的jdk是什么

[KomachiSion]

#12449

可能和这个pr有关， 之前有社区同学说sofa的hessain和caucho的hessain冲突，所以PR移除了对caucho 的 hessain的，转向统一使用sofa的hessain

sofa的hessain的概率是封装了一些caucho的hessain之后的打包，可能基础版本的caucho的hessain和之前使用的hessain版本不一致， 然后对jdk17+的支持有问题。

看下能否推动sofa-jraft解决这个问题， 如果不行的话， 下个版本回滚#12449 改动。

[reigadegr]

感谢，那我先用240版本，期待新版

[wz826]

和hessian关系不大，主要是因为nacos配置为JDK1.8，而JDK17+开始使用按模块引入包语法，不兼容之前的语法，不过一定要运行的话可以加入以下命令：
文件：nacos/bin/startup.sh
JAVA_OPT="${JAVA_OPT} --add-opens java.base/java.lang=ALL-UNNAMED "
