             Summary: mprove XRef self healing mechanism when more than one xref table
                 Key: PDFBOX-2441
                 URL: https://issues.apache.org/jira/browse/PDFBOX-2441
             Project: PDFBox
          Issue Type: Bug
          Components: Parsing
    Affects Versions: 1.8.7, 1.8.8, 2.0.0
            Reporter: Tilman Hausherr


This is a follow-up issue to PDFBOX-2250:
{quote}
the xref repair algorithm simply searches for the nearest offset, which may fail if more than one xref table is present
...
Once we have a sample pdf which can't be parsed with the simple algorithm, we can open a new issue.
{quote}
And here's one:
{code}
Exception in thread "main" java.io.IOException: Error: Expected a long type at offset 1180, instead got '50/Filter/FlateDecode/DecodeParms'
        at org.apache.pdfbox.pdfparser.BaseParser.readLong(BaseParser.java:1690)
{code}
That file does have more than one xref table.
