--------------------------------------
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:

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);
