Following #4672, #2369 and Spring Data 2024.0 Release, I expected to be able to use property placeholders in @Indexed#expireAfter.

However, this is still not possible. SpEL expressions #{...} work, as well as bean references #{@bean.method()}, but using properties ${...} results in an exception: '${ttl}' is not a valid duration, cannot detect any known style.
