> 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.
