The Java Module System in practice
summary
Shows concrete steps and gotchas for modularizing real projects: adds module-info, resolves removed JDK modules (e.g., JAXB) from Maven Central, and changes Gradle/Maven builds to put dependencies on the module path so code and tests actually run as modules. Demonstrates using jlink to produce jlink custom runtime images, handling many non‑modular jars (generate descriptors via jdeps/modularizer or merge them with the Badass JLink plugin), and packaging platform installers with jpackage installers, and confirms these approaches work on a real Vert.x app.
