A bug has existed in Spring's MergedAnnotations support since it was introduced in Spring Framework 5.2. Specifically, if the MergedAnnotations API is used to search for annotations with "standard repeatable annotation" support enabled (which is the default), it's possible to search for a repeatable annotation but not for the repeatable annotation's container annotation. The reason is that MergedAnnotationFinder.process(Object, int, Object, Annotation) does not process the container annotation and instead only processes the "contained" annotations, which prevents a container annotation from being included in search results. In #29685, we fixed a bug that prevented the MergedAnnotations support from recognizing an annotation as a container if the container annotation declares attributes other than the required `value` attribute. As a consequence of that bug fix, since Spring Framework 5.3.25, the MergedAnnotations infrastructure considers such an annotation a container, and due to the aforementioned bug the container is no longer processed, which results in a regression in behavior for annotation searches for such a container annotation. This commit addresses the original bug as well as the regression by processing container annotations in addition to the contained repeatable annotations. See gh-29685 Closes gh-32731 |
