Description

When some documents are used within a merge, it is not more possible to save the resulting PDDocument, calling method PDDocument.save() throws "java.io.IOException: COSStream has been closed and cannot be read. Perhaps its enclosing PDDocument has been closed?"

Exception in thread "main" java.io.IOException: COSStream has been closed and cannot be read. Perhaps its enclosing PDDocument has been closed?

For instance, problem occures with testPopupAnnotation.pdf when I try to merge it to testPDF.pdf (see http://svn.apache.org/repos/asf/tika/trunk/tika-parsers/src/test/resources/test-documents/ for these 2 documents)

Test.java

public static void main(String[] args) throws Exception {
	File dir = new File("D:/temp/b");

	PDFMergerUtility pdfMerge = new PDFMergerUtility();
	PDDocument targetDocument = new PDDocument();


	PDFParser ns = new PDFParser(new File(dir, "testPDF.pdf"));
	ns.parse();
	PDDocument pddDocument1 = ns.getPDDocument();
	pdfMerge.appendDocument(targetDocument, pddDocument1);
	pddDocument1.close();

	ns = new PDFParser(new File(dir, "testPopupAnnotation.pdf"));
	ns.parse();
	PDDocument pddDocument2 = ns.getPDDocument();
	pdfMerge.appendDocument(targetDocument, pddDocument2);
	pddDocument2.close();

	pdfMerge.mergeDocuments();

	FileOutputStream fout = new FileOutputStream(new File(dir, "targetDocument.pdf"));
	targetDocument.save(fout);

}
