[fuse.SDFS.SDFSFileSystem]: java.lang.NullPointerException

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Deployed Opendedup appliance 1.1.1
2. Create and mount sdfs volume (from console)
3. Share it as nfs (from console)
4. Mount the NFS share from ESX 4.0
5. Started a process which performs many writes/reads to the vmdk (mostly reads 
though).


What is the expected output? What do you see instead?
Not expecting and NullPointerException to appear. Can this cause data 
corruption or it is benign?

What version of the product are you using? On what operating system?
Opendedup appliance 1.1.1 beta
