用 JDK17 的你们的版本是怎么升上去的，升个 11 都费了老牛鼻子劲了

你发任你发，我用 java 8 。
升级是不可能升级的，这辈子都不会升级的。/斜眼笑

11

desktop: jenv.

services: jdk17 80%, jdk8 20%.

Runtime version: 17.0.6+0-17.0.6b829.9-10027231 aarch64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.
macOS 14.0

为了 zgc 也值得升级. aws 的发行版 jdk11 应该是移植了稳定版本的 zgc, 可以在 jdk11 用 zgc. 升级 jdk 后你编译级别依然可以保持 jdk1.8

坐标 日本 JDK 11
