Enhancement Request

With Shiro needing to maintain compatibility with older versions of Java,
I think there is a need to implement Multi-Release JARs.
I don't think there is any way around it because we want to use modern JDK features (like virtual threads, scoped values, etc)
while maintaining backwards compatibility

Describe the solution you'd like

Use maven plugins to accomplish this.
