org.springframework.aop.config.ConfigBeanDefinitionParser.parseAdvisor() doen't check for a missing bean name in an advisor definition.
Instead this is done ine the RuntimeBeanReference's constructor which isn't aware of the tooling API's ProblemReporter API.

java.lang.IllegalArgumentException: 'beanName' must not be empty
