             Summary: Errors parsing/saving a PDF
                 Key: PDFBOX-1757
                 URL: https://issues.apache.org/jira/browse/PDFBOX-1757
             Project: PDFBox
          Issue Type: Bug
          Components: Parsing
    Affects Versions: 1.8.2
         Environment: Ubuntu Linux & Windows 7 (both JDK6)
            Reporter: William Palmer
            Priority: Minor


I am trying to extract text from PDFs.  Extracting text from the test file http://digitalcorpora.org/corp/nps/files/govdocs1/020/020747.pdf causes exceptions to be thrown.

The first:
Exception in thread "main" java.lang.RuntimeException: java.io.IOException: Value is not an integer: 636121514401477526485946144

Caused by: java.io.IOException: Value is not an integer: 636121514401477526485946144

	at org.apache.pdfbox.pdfparser.PDFStreamParser$1.tryNext(PDFStreamParser.java:182)

Code to cause above exception:
PDFTextStripper ts = new PDFTextStripper();
PrintWriter out = new PrintWriter(new FileWriter(new File ("020747.txt")));
PDDocument doc = PDDocument.load(new File("020747.pdf").toURI().toURL(), true);
ts.setForceParsing(true);
ts.writeText(doc, out);

Using the following code causes a different exception until org.apache.pdfbox.baseParser.pushBackSize is increased (only tested 1024768).  After it is increased I get basically the same exception as above

PrintWriter out = new PrintWriter(new FileWriter(new File("020747.txt")));
PDFParser parser = new PDFParser(new FileInputStream(new File("020747.pdf")));
parser.parse();
PDFTextStripper ts = new PDFTextStripper();
ts.setForceParsing(true);
ts.writeText(parser.getPDDocument(), out);
