The new getMergedRepeatableAnnotationAttributes() method introduced in Spring Framework 6.1 ignores the classValuesAsString argument, always supplying false to Adapt.values().

https://github.com/spring-projects/spring-framework/blob/379e1f22ee421e0cb4738ec0143357b782edc850/spring-core/src/main/java/org/springframework/core/type/AnnotatedTypeMetadata.java#L220-L241

Although it's rather unlikely that anyone is adversely affected by this at this point, I'm raising the issue for discoverability in the issue tracker, and I'll fix this for 6.1.2.
