ByteBuddy in Hibernate GraalVM Issue

[tonyre]

I must apologize right away if this topic is misplaced, but please give this problem a chance to be considered.

I am using the Hibernate library (6.1.1) which includes byte-buddy (1.12.9). I would like to compile it natively using GraalVM. The compile process goes through, but at runtime an error is reported regarding byte-buddy. I have also tested different versions of hibernate and byte-buddy without any positive change.

I have tried all possible experimental options, unfortunately without success.

To easily reproduce that behavior I prepared a little sample that exactly describes that issue, please see: https://github.com/tonyre/HibernateSampleGraalVM

Maybe that's still an issue with byte-buddy - if not please appologize. Greetings Tony

Hibernate supports build-time instrumentation which I assume is required for Graal.

Have you checked Hibernates documentation?
