      Description

      Stack trace seen trying to commit a multipart upload, as the EMR code (which takes a List<String> etags is trying to sort that list directly, which it can't do if the list doesn't want to be sorted.

      later versions of the SDK clone the list before sorting.

      We need to make sure that the list passed in can be sorted.
