[jira] Created: (PDFBOX-496) PDDocument.load hangs when loading zero-length file

PDDocument.load hangs when loading zero-length file
---------------------------------------------------

                 Key: PDFBOX-496
                 URL: https://issues.apache.org/jira/browse/PDFBOX-496
             Project: PDFBox
          Issue Type: Bug
          Components: PDFReader
    Affects Versions: 0.8.0-incubator
            Reporter: Vladimir Dyuzhev


If a file passed to PDDocument.load() has zero-length (e.g. got truncated during transmission over the net), the method hangs forever.

Expected behaviour: throw an exception indicating it's not a PDF file.
