INT-4498: StreamUtils -> FileCopyUtils

JIRA: https://jira.spring.io/browse/INT-4498

* Use `FileCopyUtils` instead of `StreamUtils` in test-cases when we deal
with `InputStream` s and files resources.
* Fix reflection-based tests with AOP to use an `ArrayList` access
instead of `LinkedList` since an optimization in SF:
spring-projects/spring-framework@6d6aa72

**Cherry-pick to 5.0.x and 4.3.x**

(cherry picked from commit a1f016a)
