[Feature Request] Supporting JPMS

[arjenzhou]

Since Java 9 introduces JPMS, libs without module-info or Automatic module declaration cannot be used after Java 9, is there any plan to support it?

Thank you @arjenzhou. Yes, we definitely need this.

Looks like JPMS is still not widely adopted. Automatic-Module-Name is merely a workaround to make things work the old way. I tried multiple profiles(jre8 & jre11) in Maven, but it's difficult to release multiple jars in one go, not to mention we had to exclude different files in different profiles. As a result, I switched to multi-release jar (JEP#238, which is less flexible but a better way to manage source code and deployment. However, we still have to repackage some third party libraries like RoaringBitmap, gRPC and maybe more :<

This has been available since 0.3.2-test1.

In addition to explicit declaration in each module, Automatic-Module-Name was used for shaded jar in case it's needed somewhere.
