> Calling {{setOwner}} as a non-super user does trigger 
> {{AccessControlException}}, however, the message "Permission denied. 
> user=user1967821757 is not the owner of inode=child" is wrong. Expect this 
> message: "Non-super user cannot change owner".
> Output of patched unit test {{TestPermission.testFilePermission}}:
