> 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
> 	at org.apache.pdfbox.pdfparser.PDFStreamParser$1.tryNext(PDFStreamParser.java:187)
> 	at org.apache.pdfbox.pdfparser.PDFStreamParser$1.hasNext(PDFStreamParser.java:194)
> 	at org.apache.pdfbox.util.PDFStreamEngine.processSubStream(PDFStreamEngine.java:255)
> 	at org.apache.pdfbox.util.PDFStreamEngine.processSubStream(PDFStreamEngine.java:235)
> 	at org.apache.pdfbox.util.PDFStreamEngine.processStream(PDFStreamEngine.java:215)
> 	at org.apache.pdfbox.util.PDFTextStripper.processPage(PDFTextStripper.java:455)

> 	at org.apache.pdfbox.util.PDFTextStripper.writeText(PDFTextStripper.java:335)
> Caused by: java.io.IOException: Value is not an integer: 636121514401477526485946144
> 	at org.apache.pdfbox.cos.COSNumber.get(COSNumber.java:104)

> 	at org.apache.pdfbox.pdfparser.PDFStreamParser.access$000(PDFStreamParser.java:46)
> 	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);
