I created an empty repo https://github.com/genuss/jdk8u232-minimal with
mininal code and it breaks C2 on my machine even without Shenandoah
enabled. I attached fat-jar to release on github so you won't need to build
it https://github.com/genuss/jdk8u232-minimal/releases/tag/1.0. To run
simply use java -jar minimal-example-1.0.0-jar-with-dependencies.jar

Roman,
I tried nightly build with no luck unfortunately. Both crashes still
present.
