Sorry, but github repo listed above is compiled Java program in jar format. JVM is doing the heavy lifting here. For golang you are talking about building the program. The equivalent of it would running exe or binary format and that definitely would work unless OS/Arch version itself disappeared.

There is ton of churn in Java ecosystem package moving from javax -> jakarta namespace, new date / time/ file libs, build tool, class file format and so on. What could most likely work is standalone jar file running in older and newer JVMs.
