Error converting PS file containing PJL commands to PDF

[omasseau]

I have a ps file that contains PJL commands.
If I convert it to pdf with the command line (Ghostcript 9.20 on Windows10 64 bits) it works correctly:

gswin64c -dNOPAUSE -dBATCH -dSAFER -dProcessColorModel=/DeviceRGB -dPDFSETTINGS=/default -dCompatibilityLevel=1.4 -dPDFX=false -dDEVICEWIDTHPOINTS=612 -dDEVICEHEIGHTPOINTS=792 -sDEVICE=pdfwrite -sOutputFile=pjl.pdf -q -f pjl.ps

But it does not work with ghost4j. I get an Invalid memory access exception:

Exception in thread "main" java.lang.Error: Invalid memory access

Test code:

	public static void main(String[] args) throws Exception {
		
		try {
			String input = "C:\\postscript\\pjl.ps";
			
			PSDocument document = new PSDocument();
			document.load(new ByteArrayInputStream(Files.readAllBytes(Paths.get(input))));
			
			PDFConverter converter = new PDFConverter();

			converter.convert(document, new ByteArrayOutputStream()); 

		} catch (Exception e) {
			throw new Exception("Could not convert postscript to pdf", e);
		}
	}

Without the PJL commands it works fine.

I attached the problematic file: pjl.txt (rename extension to .ps as github does not support .ps attachments).
I also attached the file that works: no-pjl.txt

no-pjl.txt
pjl.txt
