Tilman Hausherr commented on PDFBOX-2275:
-----------------------------------------
I haven't understood the problem: does the exception (of which you didn't
include the details) happen when creating or when opening the created PDF file?
If the later, I can't reproduce it. I modified the code of ValidateXImage
(search for "loadNonSeq" in that file), and I don't get an exception:
{code}
document = PDDocument.loadNonSeq(pdfFile, null);
new PDFRenderer(document).renderImage(0);
List<PDPage> pageList = document.getDocumentCatalog().getAllPages();
PDResources resources = pageList.get(0).getResources();
resources.getXObjects();
document.close();
{code}
Like I said in the other issue - the best is to submit the shortest possible
standalone code that fails.

> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 2.0.0
> Reporter: Dominic Tubach
>
> The code (added in revision 1606860)
> {code}
> COSObject cosObject = (COSObject)dict.getItem(objName);
> {code} in the method getXObjects() in PDResources fails with a
> ClassCastException:
> bq. org.apache.pdfbox.cos.COSStream cannot be cast to
> org.apache.pdfbox.cos.COSObject
> The document issuing this exception is created using the following code:
> {code}
> PDDocument doc = new PDDocument();
> PDPage page = new PDPage();
> doc.addPage(page);
> PDImageXObject image = JPEGFactory.createFromStream(doc, imageStream);
> try (PDPageContentStream contentStream = new PDPageContentStream(doc, page,
> false, false)) {
> contentStream.drawImage(image, 20, 20);
> }
> {code}
