Strict validation closes stream

Aspose.PDF Product Family
1

Hi
I can use the same stream for both Document and PdfFileInfo, but not if I set UseStrictValidation=true, then the stream seems to be closed which was not expected.
By design or a bug? If by design I have to have two copies of the PDF in memory.

Thanks,
Jacob

Hi
I believe any PDF will cause crash, so not attaching any here.

The following code can be used to replicate the crash

            String filepath = "<path to some pdf>";
            using (MemoryStream stream = new MemoryStream(File.ReadAllBytes(filepath)))
            {
                    using (Document pdfDocument = new Document(stream))
                    {
                        using (var info = new Aspose.Pdf.Facades.PdfFileInfo(stream))
                        {
                            info.UseStrictValidation = true;
                            var v2 = info.IsPdfFile;            // causes the crash later on, but only when UseStrictValidation is true
                        }

                        for (int i = 1; i <= pdfDocument.Pages.Count; i++)
                        {
                            Page page = pdfDocument.Pages[i]; // Crash! System.ObjectDisposedException: 'Cannot access a closed Stream.'
                        }
                    }
                }
            }
