Memory leak in CommonAnnotationBeanPostProcessor [SPR-17127]

[spring-projects-issues]

Timur Strekalov opened SPR-17127 and commented

org.springframework.context.annotation.CommonAnnotationBeanPostProcessor#findResourceMetadata puts metadata into the org.springframework.context.annotation.CommonAnnotationBeanPostProcessor#injectionMetadataCache, but nothing ever cleans it, leading to a memory leak in case bean definitions for beans with different names get added and removed. This is particularly visible when using Spring Integration's dynamic flows.

Note that this issue could be considered a duplicate of #21663, since the code for findResourceMetadata and findAutowiringMetadata is exactly the same, but I figured I'd report two separate issues anyway.

Let's treat it as a duplicate since the mechanism introduced for #21663 is generic at the MergedBeanDefinitionPostProcessor level, applying to Autowired as well as Common and PersistenceAnnotationBeanPostProcessor.
