Jeremy Anderson commented on TIKA-733:
--------------------------------------
Cool beans!!
Thanks for your attention to it. Yeah, I confirmed with 18 of the other files
experiencing this error, all corruption issues similar to the first one.
Although the amount of info contained in the final block varies widely from a
few chars to none.
But using the patch I already submitted does appear to actually work with
getting the text out for each these corrupted documents.
Thanks again for adding it to the trunk.

>
>
> Parsing some RTF documents attempt to perform a removeLast() on the
> groupStates() list when the list is empty. Added a check to not perform the
> logic when the list is empty, thus causing the restore group state to not be
> performed. Text extraction now completes without further down-stream errors.
> Unable to include sample file due to sensitive nature of file contents.
