Any updates here? Some cglib generated proxy classes keep reference to BeanFactory, so BeanFactory can't be garbage collected, and memory footprint grows and grows. It is the most sensitive in...

I wouldn't say that problem is only in `MethodSecurityMetadataSourceAdvisor`. In our application I also see reference from `RetryConfiguration`:  And such chain(related to `RefreshScope`) keeps reference to `GenericWebApplicationContext` . 

@velo please have a look. I didn't add test into LoggerTest because it is used as parent, so decided to create new test class

As a workaround I created custom convention, which provides same key names like spring for WebClient/RestTemplate https://gist.github.com/Nazukin-Dmitry/c020cf8c71adccde7186a89e5bad7989
