Using spring-retry @EnableRetry with spring-batch causes unexpected proxy

Question

I am trying to make use of the spring-retry library in my batch job and on adding the @EnableRetry annotation to my @Configuration as documentation suggests my application is now failing because it appears a spring-batch library bean which is being @Autowired is being proxied.

@Configuration
@EnableBatchProcessing
@EnableRetry
@Import({SpringBatchConfiguration.class, School192ClientConfiguration.class })
public class SchoolJobConfiguration { .. }

Exception:

Caused by: org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'jobRegistry' is expected to be of type 'org.springframework.batch.core.configuration.JobRegistry' but was actually of type 'com.sun.proxy.$Proxy130'

I have added the following to a separate class:

@Retryable(value = School192ClientException.class, maxAttempts = 3, backoff = @Backoff(delay = 2000))
@Override
protected void doReadPage() {

My question is why is this bean (jobRegistry) being proxied? (I don't have much experience with AOP).

I am using spring-boot version 1.5.3.RELEASE.

Spring Boot is auto configuring that for me. Upgrading my version of spring-retry to 1.1.5.RELEASE and spring-boot to 1.5.7.RELEASE seems to rid me of the problem. (though I am no better off understanding the original cause) — dapperwaterbuffalo, Oct 04 '17 at 11:05
The likely problem was the combination of using java proxies and cglib proxies which is why I was asking where it was configured. — Michael Minella, Oct 04 '17 at 15:30
I am using spring boot and the spring boot batch starter, which is wiring all that for me. I couldn’t see any annotations which I would expect to make that class a candidate for proxying but maybe thats my lack of understanding? — dapperwaterbuffalo, Oct 04 '17 at 16:31
