[jira] [Created] (PDFBOX-3612) ScratchFileBuffer not closed message
related to overlay.overlay(overlayGuide);
André Heuner created PDFBOX-3612:
------------------------------------
Summary: ScratchFileBuffer not closed message related to overlay.overlay(overlayGuide);
Key: PDFBOX-3612
URL: https://issues.apache.org/jira/browse/PDFBOX-3612
Project: PDFBox
Issue Type: Bug
Affects Versions: 2.0.3
Environment: Windows 7 Professional, Eclipse, JDK 1.8
Reporter: André Heuner
Priority: Minor
I'd like to add a watermark to a PDF and have the following code:
PDDocument pdfDocument = PDDocument.load(new
PDDocument pdfCopy = Pdf.addWatermark(pdfDocument);
pdfDocument.close();
pdfCopy.close();
....
public static PDDocument addWatermark(PDDocument document) {
try {
HashMap<Integer, String> overlayGuide = new HashMap<Integer, String>();
for(int no = 0; no < document.getNumberOfPages(); no++){
overlayGuide.put(no +1, "C:\\Software\\watermark.pdf");
}
Overlay overlay = new Overlay();
overlay.setInputPDF(document);
overlay.setOverlayPosition(Overlay.Position.FOREGROUND);
PDDocument result = overlay.overlay(overlayGuide);
document.close();
overlay.close();
return result;
} catch (Exception e) {
log.error("Error while adding watermark: " +e.getMessage(), e);
return document;
}
}
overlay.overlay(...) seems to cause lot's of warnings:

Is there anything, that can be done to fix this issue? I tried to close anything that is closable - but the issue remains. Or can it safely be ignored?
