Show project for spring native bug - spring-data-mongodb gives cglib error for interface referenced beans

When org.springframework:spring-tx is imported, java native projects with repository beans defined with interface types will encounter exception in runtime about unexpected CGLIB usage for the repository class.

Steps for reproduction

1. Compile ./mvnw clean package -Pnative -DskipTests
2. Run ./target/demo

• Usually, when a bean is defined with interface type, cglib proxy is not necessary
  • process-aot does not generate MongoDao$$SpringCGLIB$$0.class class in target/spring-aot/main/classes.
• however, in runtime, something is trying to wrap MongoDao with CGLIB proxy in runtime, resulting in below exception.

Expected behaviour

Either

• stop referencing cglib classes in native runtime for my interface-defined repository bean

Or

• update spring-aot to pre-generate cglib classes for repository beans even they are defined with interface types

Known workarounds

• Define all repository beans with concreate type at BeanConfig, see code comments.

Used Versions

• JDK: 21.0.2-graalce
• Spring-Boot: 3.4.2 (latest to date)
• MacOS 15.2 on ARM64 mac
