            Description


            The document in question contains an xref table that contains all zero byte offsets for the respective document objects. We have code that can adjust for the small errors in the offset values but this is a corner case that does't trigger the secondary fallback code that will parse the file from start to finish.

            For the ongoing 4.5 and 5.0 work we need to take into consideration this corner case.

              The Document class and supporting xref classes where reworked to keeps track of object offsets and rebuild the xref table during a linear traversal. Closing issue.
