[PATCH] RTF TextExtractor processGroupEnd() NoSuchElementException
------------------------------------------------------------------
Key: TIKA-733
URL: https://issues.apache.org/jira/browse/TIKA-733
Project: Tika
Issue Type: Bug
Components: parser
Affects Versions: 1.0
Reporter: Jeremy Anderson
Fix For: 1.0

TIKA-733-rtf_TextExtractor_processGroupEnd-NoSuchElementException.patch
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.
