The purpose of this repository is to create native PlantUML images (optimized for Kroki).
It seems that the latest version of GraalVM provided by OpenJDK does not work with PlantUML:

As a workaround, the GraalVM distribution by Bellsoft seems to produce working native images: https://bell-sw.com/pages/downloads/native-image-kit/#nik-23-(jdk-21)
