#77 No support for Multi-Release Jars

[Gus Heck]

Multi-release artifacts not finding their MR components. The specific case of primary interest is the newer versions of Log4J which output the following:

WARNING: sun.reflect.Reflection.getCallerClass is not supported. This will impact performance.

Adding Multi-Release: true to the Manifest does not solve the problem as it should (see https://stackoverflow.com/a/54713830)

I'm aware that this project is not updated anymore, but this is useful info for anyone considering using it.
