Maybe I am too late to answer. But you should have a look at Tika. It uses PDFBox Parser internally to parse PDF's

You just need to import tika-app-latest*.jar

 public String parseToStringExample() throws IOException, SAXException, TikaException 
 {

      Tika tika = new Tika();
      try (InputStream stream = ParsingExample.class.getResourceAsStream("test.pdf")) {
           return tika.parseToString(stream); // This should return you the pdf's text
      }
}

It would be a much cleaner solution . You can refer here for more details of Tika Usage : https://tika.apache.org/1.12/api/
