Does Project Lombok support Java 9?

The Lombok project has an issue tracking Java 9 support. As of January 9th 2018 and version 1.16.20, Lombok officially supports Java 9. From the changelog:

• PLATFORM: Better support for jdk9 in the new IntelliJ, Netbeans and for Gradle.
• BREAKING CHANGE: lombok config key lombok.addJavaxGeneratedAnnotation now defaults to false instead of true. Oracle broke this annotation with the release of JDK9, necessitating this breaking change.
• BREAKING CHANGE: lombok config key lombok.anyConstructor.suppressConstructorProperties is now deprecated and defaults to true, that is, by default lombok no longer automatically generates @ConstructorProperties annotations. New config key lombok.anyConstructor.addConstructorProperties now exists; set it to true if you want the old behavior. Oracle more or less broke this annotation with the release of JDK9, necessitating this breaking change.
• DEVELOPMENT: Compiling lombok on JDK1.9 is now possible.

(At the moment, it is no module, though, so you need to place it on the class path. Thanks Tos’ answer, which first mentioned this.)
