INT-3218 Spring 4 Compatibility

Use `Arrays.asList()` instead of `Collections.arrayToList()` in
places where a generic type needs to be supplied by the caller.

This maintains compile-time compatibility with both Spring 3 and 4,
where Spring 4 added the generic type to the utility class.

The four occurrences where this was needed are not impacted
by the fact that `Arrays.asList()` returns an unmodifiable list.
