Spring JPA query returns List<PageImpl>, when the repository return type is List<Post>

From what I understand, this should not be possible in the first place. A generic is supposed to prevent this from happening. When I try to access the list, I get an InvocationTargetException (probably since it expects Post). This is the relevant section from my code:

List<Post> posts;

Sort sort = new Sort(new Sort.Order(Sort.Direction.DESC, "dateCreate"));
Pageable pageable = new PageRequest(pageIndex, pageSize, sort);

posts = postRepository.findAll(pageable);

This is the function in my repository:

List<Post> findAll(Pageable pageable);

The list that is actually returned contains one PageImpl, and the PageImpl contains the List<Post> that was supposed to be returned in the first place.

Try : 

Page<Post> findAll(Pageable pageable);

And convert it to list: 

List<Post> postList =  x.findAll(page).getContent();
