Eric Charles commented on MAILBOX-48:
-------------------------------------
What to do if uid file is corrupted ?
Manually remove it, so maildir will regenerate it ?
Could the code remove the file (File.delete()) ? (after all, it is corrupted...)
> Detect corrupted uid file and throw checked exception

> At the moment we try to parse the uid file and split lines on "gaps" to read
> the uid list. It happened to me that I had a corrupted line in the file
> (don't know yet why) which raised a IndexOutOfBoundException later (because
> the gap position was detected as -1). It would be nice if we throw an checked
> exception in this cases which contains the file + linenumber which raised
> this problems.
