Steps to reproduce:
git clone https://github.com/Ledmington/emu.git cd emu ./gradlew readelf:fatjar cp readelf/build/libs/emu-readelf.jar . wget https://github.com/unimined/JvmDowngrader/releases/download/0.8.3/jvmdowngrader-0.8.3-all.jar java21 -jar jvmdowngrader-0.8.3-all.jar -c 52 downgrade -t emu-readelf.jar output.jar java8 -jar output.jar
The output is this:

Not sure if it may help, but it gives the same error when trying to run it with java 21.
Unfortunately I wasn't able to create a minimal non-working example but, judging from the error, it seems that the problem may be realated to this.
