            Description

            The PDF in question has several Errors in the byte offsets defined in the xref table. Generally speaking ICEpdf should detect the error and start a full document parse, locating all the objects in the file. For some reason the fall back code isn't getting executed and page loading fails. It should be noted that acrobat displays a few errors when loading the document.

            Tasks for this bug.
            - figure out why the fallback code isn't executing
            - consider an parser enhancement, instead of parsing the whole file into memory on failure, we should consider updating the xref table with new byte offset found by parsing file, but not keeping the objects in memory.
