Spring data repositories not working after enabling Spring AOP [JAVA 11]

Question

Hi I have an application using Spring 5, Spring Data and Spring AOP and Java 11 (I am using JAVA 9 module system as well). My spring-context/spring-aspects version is 5.1.2.RELEASE Spring Data version is 2.1.2.RELEASE Both the versions are the latest available. I have created repositories in following manner:

@Repository
public interface AirportRepository extends JpaRepository<Airport, Long> {
}

I have enabled Spring Data Repositories using

@Configuration
@EnableTransactionManagement
@PropertySource("classpath:persistence-jndi.properties")
@PropertySource("classpath:hibernate.properties")
@EnableJpaRepositories(basePackages = "com.xx.yy.persistence")
public class PersistenceJNDIConfig {
  //Datasource configs
}

It was working perfectly until I introduced Spring AOP, using following configuration.

@ComponentScan(basePackages = "com.xx.yy")
@EnableAspectJAutoProxy(exposeProxy = true)
public class AdminServicesConfiguration {
}

And

@Aspect
@Component
public class DasErrorHandler {

    @Around("@target(com.xx.yy.commons.aop.ErrorManagedDAS)")
    public Object handle(ProceedingJoinPoint proceedingJoinPoint){
        //Some code
    }
}

But now on server startup I am getting following error:

Caused by: java.lang.IllegalStateException: Cannot convert value of type 'com.sun.proxy.$Proxy82 implementing org.springframework.data.util.Streamable,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised,org.springframework.core.DecoratingProxy' to required type 'org.springframework.data.repository.core.support.RepositoryComposition$RepositoryFragments' for property 'repositoryFragments': no matching editors or conversion strategy found

    at org.springframework.beans.AbstractNestablePropertyAccessor.convertIfNecessary(AbstractNestablePropertyAccessor.java:585)
    ... 103 more

It seems there is a mismatch in the proxy types generated by Spring which is causing the above error, I tried forcing spring to use CGLIB proxies by making:

@EnableAspectJAutoProxy(exposeProxy = true, proxyTargetClass = true )

then the error changes to following, even when I have SpringProxy class on my classpath. Please help:

Are you [using a compatible version of Spring with Java11](https://stackoverflow.com/questions/51427248/minimum-spring-version-compatible-with-java-11/51429027#51429027) ? — Naman, Nov 10 '18 at 09:25
@Antoniossss This is Spring AOP using AspectJ annotations. Spring supports AspectJ annotations. — Abhisar, Nov 10 '18 at 09:47
@nullpointer Yes I am, I have updated the question with versions — Abhisar, Nov 10 '18 at 09:49
@Abhisar Since [you're creating a modular project](https://stackoverflow.com/questions/53237556/spring-data-repositories-not-working-after-enabling-spring-aop-java-11#comment93361595_53237771), can you also share your module declarations and dependencies (with versions) in use? — Naman, Nov 10 '18 at 11:55
@nullpointer I have highlighted the versions and added module-info.java now — Abhisar, Nov 10 '18 at 12:53
Judging from the stack trace you mis the requires for the commons-dbcp2 project. — M. Deinum, Nov 10 '18 at 13:01
@ M. Denim : it didnt work even after that....as I have mentioned in the question that, it was working before integrating spring aop. So it should not be a dependency issue. — Abhisar, Nov 10 '18 at 13:15
Aside: You can make sure, the spring dependency bring in a [compatible version of aspectJ](https://www.eclipse.org/aspectj/doc/released/README-192.html) as well. — Naman, Nov 11 '18 at 02:17
@nullpointer It is compatible....Finally I had to ditch spring AOP and use pure AspectJ instead. — Abhisar, Nov 27 '18 at 08:26

Try adding AOP lib to your dependencies

<!-- https://mvnrepository.com/artifact/org.springframework/spring-aop -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aop</artifactId>
    <version>5.1.2.RELEASE</version>
</dependency>

Its already present. Also, I have included it in module-info.java – Abhisar Nov 10 '18 at 09:51
