title: Ghost4J - EXCEPTION_ACCESS_VIOLATION (JVM is crashing)
body: <p>I'm trying to replace the PDF converter we are using in the company, but I'm getting this issue with Ghost4J. Note my code is very similar to the sample they provide... </p>
  
  <p>I'm using Java SE 1.6 (jrockit-jre1.6.0_33-R28.2.4) and Ghostscript 9.10 for Win 64 bits.</p>
  
  <p>My code is:</p>
  
  <pre><code>public void convertPostScriptToPDF() {
          File file= new File (this.getClass().getResource( "/resources/employer_report_last_page.ps").getFile());
          FileOutputStream fos = null;
          try{
  
              //load PostScript document
              PSDocument document = new PSDocument();
              document.load(file);        
  
              fos = new FileOutputStream(new File("rendition.pdf"));    
              //create converter
              PDFConverter converter = new PDFConverter();
  
              //set options
              converter.setPDFSettings(PDFConverter.OPTION_PDFSETTINGS_PREPRESS);
  
              //convert
              converter.convert(document, fos);
  
          } catch (Exception e) {
              System.out.println("ERROR: " + e.getMessage());
          } finally{
              IOUtils.closeQuietly(fos);
          }
      }
  </code></pre>
  
  <p>The JVM crash, that occurs on "converter.convert(document, fos);" displays on the dump file the message:</p>
