> Jeff Jirsa added a comment - Yesterday
> Aleksandr Ivanov can you open a new JIRA and link it back to this one? It's 
> possible that the original patch didn't consider 0 byte files (I don't have 
> time to go back and look at the commit, and it was long enough ago that I've 
> forgotten) - were all of your files 0 bytes?
> Not all, 8..10 hints files were with 0 size.
