I am trying to convert a .docx file to .pdf with Docx4J. I get this error:

This exact error message only appeared once on Google Search and there was no sign of Docx4J there.
Code:
String tag = "Docx4J Test";
try {
WordprocessingMLPackage mlPackage = WordprocessingMLPackage.load(getFilesDir().toPath().resolve("template-default.docx").toFile());
mlPackage.save(getFilesDir().toPath().resolve("result.docx").toFile());
Log.d(tag, "SAVED");
FileOutputStream outputStream = new FileOutputStream(getFilesDir().toPath().resolve("result.pdf").toFile());
Docx4J.toPDF(mlPackage, outputStream);
Log.d(tag, "SUCCESS");
} catch (Docx4JException | FileNotFoundException e) {
Log.d(tag, "onCreate: ".concat(e.getMessage()));
}
I added those dependencies to app/build.gradle:
implementation("org.docx4j:docx4j-JAXB-ReferenceImpl:8.3.3") {
exclude group: "commons-logging"
}
implementation "com.fasterxml:aalto-xml:1.3.2"
implementation "javax.xml.stream:stax-api:1.0-2"
implementation files("libs/awt-bastardised-17v8.jar") // https://github.com/plutext/Docx4j4Android4/blob/master/app/libs/awt-bastardised-17v8.jar
implementation("org.docx4j:docx4j-export-fo:11.4.8") {
exclude group: "org.apache.xmlgraphics"
}
implementation "org.glassfish.jaxb:jaxb-runtime:4.0.3"
Changing to MOXy didn't work - same error. I tried downgrading jaxb-runtime but got a different error.
Here's the full example so you can run it yourself: https://github.com/Volper212/docx4j-test
Keep in mind that in order to run this you need a template-default.docx file in the files directory of the app (/data/user/0/com.example.docx4jtest/files/template-default.docx). This can be any valid .docx file.
To get to this point, I used, among others, these resources:
