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.
