Bug description
java.lang.ClassCastException: class org.springframework.data.domain.SliceImpl cannot be cast to class org.springframework.data.domain.Page (org.springframework.data.domain.SliceImpl and org.springframework.data.domain.Page are in unnamed module of loader )

Environment
Spring Batch version: 5.6.0, Java: 17, Database: couchbase, postgresql

Steps to reproduce
Create respository with method: Slice<T> findAll(Pageable pageable) and use it in own RepositoryItemReader

Expected behavior
It is expected that everything will work as in the case of Pageabla

How has this issue affected you?
Performance degradation in fetching data from couchbase

Are you aware of any workarounds?
Change in org/springframework/batch/item/data/RepositoryItemReader.java:223
Page<T> curPage = (Page<T>) doInvoke(invoker);
with
Slice<T> curPage = (Slice<T>) doInvoke(invoker);
