如果用其它支持JDK17序列化协议是可以的
当前bolt 使用的默认序列化协议是hession，部分类（如AtomicXXX）会有问题，不过这个在支持中 https://github.com/sofastack/sofa-hessian/pulls

sofa.hessian 目前已经发布了3.5.0 版本. Bolt是不是就已经支持Java17了?

@Lo1nt is java 17 officially supported?

@chuailiwu @Lo1nt
同问，事实hessian已经支持jdk17了的。目前我们是在springboot3.2下使用的。但是由于日志框架需要2.x版本，只发现了使用会出现一下错误

@chuailiwu @Lo1nt 我在另外一个框架sofa-jraft升级到jdk17。发现集群启动正常，但是他CliService工具会提示Connection is null when do check!。我感觉应该也是这边问题。还是希望尽快升级下jdk。

hession 已经升级到了3.5.3
另你这个问题应该和jdk17没关系，你可以看下调用栈，只是要做目标地址的连接检查，如果没有也不会创建
