Description

Need to search for a correct xref start address

Example file:
http://digitalcorpora.org/corp/nps/files/govdocs1/020/020747.pdf

Exception in thread "main" java.io.IOException: Error: Expected an integer type, actual='ref'
at org.apache.pdfbox.pdfparser.BaseParser.readInt(BaseParser.java:1622)

Using the code:
PDFTextStripper ts = new PDFTextStripper();
PrintWriter out = new PrintWriter(new FileWriter(new File (pFile+".txt")));
RandomAccess scratchFile = new RandomAccessFile(File.createTempFile("pdfbox-", ".tmp"), "rw");
PDDocument doc = PDDocument.loadNonSeq(new File(pFile), scratchFile)
ts.setForceParsing(true);
ts.writeText(doc, out);
