I havent fully looked into why the hibernate validator is still present but if it is needed still, we need to be sure to update the RuntimeHintsConfiguration.java for at least rest java (and probably web3) to include additional hints.

registerReflectionTypes(hints, CONSTRUCTORS_ONLY, Log_$logger.class); needs to become registerReflectionTypes(hints, CONSTRUCTORS_ONLY, Log_$logger.class, Messages_$bundle.class);

RuntimeHintsConfiguration is updated as requested.
Otherwise all annotations that are coming from the jakarta.validation-api , like Min,Max,Size,Valid, etc. are implemented by the hibernate validator. We can probably get rid of it by providing our implementation, but it isn't worth it considering the space we are going to save is quite small (hibernate-validator-9.0.1.Final.jar is 1.3 MB).
