             Summary: Not correct support of incremental save
                 Key: PDFBOX-2981
                 URL: https://issues.apache.org/jira/browse/PDFBOX-2981
             Project: PDFBox
          Issue Type: Bug
          Components: Writing
    Affects Versions: 2.0.0
            Reporter: Evgeniy Muravitskiy


When write code like follows:
{code}
try {
			PDDocument document = PDDocument.load(new File(SOURCE_PATH));
			// SOME_OBJECT is not object number of catalog, info dictionary or encrypt
			COSObjectKey key = new COSObjectKey(SOME_OBJECT, 0);
			COSObject objectFromPool = document.getDocument().getObjectFromPool(key);
			COSDictionary object = (COSDictionary) objectFromPool.getObject();
			object.setItem(COSName.getPDFName("Test"), COSBoolean.TRUE);
			object.setNeedToBeUpdated(true);
			OutputStream writer = new BufferedOutputStream(new FileOutputStream(OUTPUT_PATH));
			document.saveIncremental(writer);
			writer.close();
			document.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
{code}
in result file I`ve got nothing. It`s related with next problem: when we use {{PDDocument.save(OutputStream)}} - {{OutputStream}} is real output stream (for example, {{FileOutputStream}} or {{BufferedOutputStream}}), but incremental save use {{ByteArrayOutputStream}} which not store data in some file and only keep it in memory. Also when save is incremental data from source file is not send to result file.
