How to get java8 code that uses Unsafe running on jdk8 and jdk9?

Question

I use sun.misc.UnsafeJava8 in my code base. This does not work on Java9.

I would like to have a fix for Java9, but with the same code base that runs on Java8. If I put module-info.javathis will not work, since my code base is Java8.

What to do?
