Cannot process AOT when spring-orm is on the classpath without JPA

[filiphr]

If I create a basic Spring Boot project using https://start.spring.io/#!type=maven-project&language=java&platformVersion=3.2.2&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo&dependencies=native and I add the spring-orm dependency

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-orm</artifactId>
</dependency>

then when I run ./mvnw spring-boot:process-aot I am going to get:

Is it possible to move the PersistenceManagedTypesBeanRegistrationAotProcessor#CALLBACK_TYPES in the PersistenceManagedTypesBeanRegistrationAotProcessor.JpaManagedTypesBeanRegistrationCodeFragments. Those are anyways only used in the JpaManagedTypesBeanRegistrationCodeFragments and I believe if they are moved the exception will be gone.

@filiphr we're going to obviously fix that but can you share why you are running AOT (on an application) with only spring-orm on the classpath?

[filiphr]

Thanks @snicoll. Sorry, I should have explained a bit more in the original issue. The example I shared is the minimal example where this is happening.

I noticed this while I was working on integrating the PR from @joshlong and @jbarrez for integrating Native Support in Flowable (flowable/flowable-engine#3815). I am using https://github.com/spring-tips/flowable-processes as a test and moving that into the Flowable project. I wanted to remove the dependency to spring-boot-starter-data-jpa and I saw the stacktrace. It looks like our spring module is using spring-orm, I need to investigate whether we can remove that. Hope this clarifies how I found this issue.

I wasn't really asking how you found the issue but I was more curious why you'd be using AOT with such an environment. Running your tests in a native image is answering that question. Thanks!
