Aspect Around Transactional service throw UnexpectedRollbackException

Question

I Have Aspect around Methods in Transactional service. Unfortunately, when I catch errors by service, another exception is throwed. How can I prevent from this error ? *I searched for similar question but no-one solutions seems be adequat for my case

@Aspect
@Component
public class ServiceGuard {   
    @Pointcut("execution(* simgenealogy.service.*.*(..))")
    public void persistence() {}

    @Around("persistence()")
    public Object logPersistence(ProceedingJoinPoint joinPoint) { 
        try {
            Object o =  joinPoint.proceed();
            return o;
        } catch (ConstraintViolationException constraintException) {
            // (...)
            return null;
        } catch (Throwable throwable) {
            // (...)
            return null;
        }
    }
}

And error log.

Ok I found solution. @Transactional is also @Arround Aspect. The problem was in ordering aspects. My Guard class wasn't in fact around Transaction. Put @Order(0) on Guard and @Order(1) on @Transactional service solved issue.
