module-info.java

Please add Java9+ support by adding module-info.java to this library.

Using the multi-release JAR approach, you can maintain backwards compatibility to older versions of Java. See the multiReleaseOutput property in https://www.baeldung.com/maven-multi-release-jars for the easiest way to proceed.

Hi, I'll add Automatic-Module-Name entry.

For multi version support, currently datasource-proxy supports java6 and up.
It wouldn't be a good fit to support a wide range of new language features available in the newer java versions.
I'll rather take a baseline upgrade in the next major version of datasource-proxy(TBD).

Hi @ttddyy

Can you please elabroate? What's the problem with adding META-INF/versions/9/module-info.class? This won't break anything for anyone using older versions of Java.

Unfortunately, automatic modules are not equivalent to full-fledged modules. They trigger warnings when building Maven and cannot be used with jlink, etc.

Let me know about the above question. Hopefully we can find a way forward.
