해결

I posted my question on the Spring Data JPA JIRA as a bug report and the issue was apparently observed before. After some discussion on there I now use @Transactional on the Stream related code to resolve the issue as a workaround. Thanks goes to Oliver Gierke for pointing this out here:

JPA에서 Stream을 사용하는 경우 버그가 발생한다. Service 상단에 @Transactional(readOnly=true)을 추가하여 해결할 수 있다.
