Description

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.
