> * this is the normal readFully() call, before the vectored one
> * it worked last week
> * also found on branch-3.4 before the SDK update, so not an issue caused by
> the SDK unless my maven repo is badly contaminated
> * seems unrelated to versioning -still there when disabled.
> * applies on unversioned s3 express store too.
> About the main way I could see this surface is if the test file is less than
> the actual length of file created, so the GET is rejected for reading off the
> end (the openfile passes in the length to save the HEAD)
