Ghost4J - EXCEPTION_ACCESS_VIOLATION (JVM is crashing)

Question

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...

I'm using Java SE 1.6 (jrockit-jre1.6.0_33-R28.2.4) and Ghostscript 9.10 for Win 64 bits.

My code is:

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);
        }
    }

The JVM crash, that occurs on "converter.convert(document, fos);" displays on the dump file the message:

Error Message: Illegal memory access. [54]

Any ideas? Thank you in advance, Thais

Answer 1

public synchronized void convertPostScriptToPDF()

or

public void convertPostScriptToPDF() { synchronized(this) { ... } }

Answer 2

My thoughts is that my issue is related in someway to UAC on windows OS as mentioned on http://www.java.com/en/download/help/exception_access.xml, but changing as suggested didn't solve the issue. Anyway, through a workaround I got my issue solved. See below I'm using the core API instead of the high level one:

public void convert() {

        //get Ghostscript instance
        Ghostscript gs = Ghostscript.getInstance();

        File file= new File (this.getClass().getResource( "/resources/employer_report_last_page2.ps").getFile());//(Config.EMP_REPORT.REPORT_LAST_PAGE_STORE_PATH);
       // File file= new File (this.getClass().getResource( "/resources/Issues.ps").getFile());

        //prepare Ghostscript interpreter parameters
        //refer to Ghostscript documentation for parameter usage
        String[] gsArgs = new String[10];
        gsArgs[0] = "-ps2pdf";
        gsArgs[1] = "-dNOPAUSE";
        gsArgs[2] = "-dBATCH";
       gsArgs[3] = "-dSAFER";
        gsArgs[4] = "-sDEVICE=pdfwrite";
        gsArgs[5] = "-sOutputFile=output2.pdf";//output file name
       // gsArgs[5] = "-sOutputFile=" + file.getAbsolutePath();
        gsArgs[6] = "-c";
        gsArgs[7] = ".setpdfwrite";
        gsArgs[8] = "-f";
       // gsArgs[9] = "input.ps";//input file name
        gsArgs[9] = file.getAbsolutePath();//input file name

        //execute and exit interpreter
        try {

            gs.initialize(gsArgs);               
            gs.exit();

        } catch (GhostscriptException e) {
            System.out.println("ERROR: " + e.getMessage());
        }
 }
