v1.4.0-RC1

Added

• Add support for JSpecify annotations for nullability and Kotlin interop.
• Add support for Java Platform Module System. For problem4j-jackson2 support is included by producing multi-release JAR artifact, so Java 9+ picks module information and Java 8 ignores it.

  module org.example.project {
      // pick what you need for your project
      requires io.github.problem4j.jackson2;
      requires io.github.problem4j.jackson3;
  }

Changed

• Bump problem4j-core to 1.4.0-RC1.
