[Building Sakai] [DATA LOSS] 2.9 DAV MOVE zeroes out files?!

[Aaron Zeckoski]

If you can reproduce it against stock 2.9.1 then I think you probably
should create a JIRA for it. It sounds like it might be a 2.9.2
release blocker if it actually results in data loss. Can you check and
see if the files are overwritten or just that the old ones are not
actually moving and the new ones are empty?
