I am trying to figure out how to use PDFBox (2.0.30) to render image from a PDF document in a native application based on Spring Boot (3.2.1).
PDF generation works fine, but image rendering fails. when I try to convert a PDocument into an image using the PDFRenderer#renderImage(int, float), there is the following error:

The Spring Webflux Application (awt-native-test) is a native executable built with the Native Maven Plugin:
mvn native:compose -Pnative
To run it:
./target/awt-native-test
Java Version:
openjdk version "21.0.1" 2023-10-17 LTS
OpenJDK Runtime Environment Liberica-NIK-23.1.1-1 (build 21.0.1+12-LTS)
OpenJDK 64-Bit Server VM Liberica-NIK-23.1.1-1 (build 21.0.1+12-LTS, mixed mode, sharing)
I guess I have to declare several runtime hints for Java2D to use PDFBox (something like hints.jni().registerType(ShapeSpanIterator.class, MemberCategory.values());), however I do not known how to do it as sun.java2D.pipe code is not exported by the module.
What am I missing ? Is image rendering from PDFBox native-ready ?
Code to reproduce my problem is here: https://github.com/nicolasjanet/awt-native-test
I ran my app using the tracing agent to get the missing hints, and I end up adding these hints using TypeReference in my RuntimeHintsRegistrar implementation:
// Java2D
hints.jni().registerType(TypeReference.of("sun.java2d.pipe.ShapeSpanIterator"), MemberCategory.values());
// JPEG
hints.jni().registerType(TypeReference.of("sun.awt.image.ByteComponentRaster"), MemberCategory.values());
hints.jni().registerType(TypeReference.of("com.sun.imageio.plugins.jpeg.JPEGImageWriter"), MemberCategory.values());
hints.jni().registerType(JPEGQTable.class, MemberCategory.values());
hints.jni().registerType(JPEGHuffmanTable.class, MemberCategory.values());
