title: PDF extraction issue with apache PDFBox 1.3.1
body: <p>I am facing some issue while extracting data from PDF using apache PDFBox.
  With PDFBox version 1.1, i was able to extract the data properly. But the same code is giving different output with version 1.3.1. Only for few PDFs,
  I am facing this issue.</p>
  
  <h2>Code sample</h2>
  
  <pre><code>PDDocument document = PDDocument.load(new File("sample.pdf"));
  PDFTextStripper stripper = new PDFTextStripper();
  stripper.setSortByPosition( true );
  System.out.println(stripper.getText(document));
  </code></pre>
  
  <p>Here is the sample output:</p>
  
  <blockquote>
