Hi, I think this is a limitation of the runtime: Hibernate will need those proxies, and it’s not allowed to create them since the BytecodeProvider has been disabled.

I’ve already resolved this issue for Quarkus, feel free to have a look: https://hibernate.atlassian.net/browse/HHH-13804; essentially you need to ensure the right proxies are generated upfront, so that the classes can then be compiled by GraalVM.
