I was able to reproduce on with 3.8 using Ubuntu 13.04 running in KVM 
using the commands exactly as given, but it only after stopping and 
starting the server again.

I use the cloud image from here, boot of an Ubuntu CD-ROM ISO to change 
from ext4 to btrfs, then installed openjdk.

http://cloud-images.ubuntu.com/raring/current/raring-server-cloudimg-amd64-disk1.img

I could make my image available for download later if you need it, in a 
pre-failure state.  Let me know.
