Thanks for filling a bug.

This means that the d8 tool didn't run correctly.
I have no idea why this is the case though.

Same problem, same (older patch) java version

java version "11.0.19" 2023-04-18 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.19+9-LTS-224)

In my case, this is a problem with the d8 tool itself, up on running ./d8 it outupts

-Djava.ext.dirs=C:\Users\...\android-sdk-33\build-tools\33.0.2\lib is not supported.  Use -classpath instead.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

And this fix worked fine for me, it's not ideal since you need to edit d8.bat but it does fix the issue

[ogoffart]

Maybe we should actually run the d8.jar directly from the build script instead of relying on the .bat script.
