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

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:
