PdfContentEditor closes a document that it has not opened

Hello

I use the PdfContentEditor to copy viewer preferences from a source pdf to a cloned pdf with this code using the last library aspose-pdf-22.2.jar :

try (PdfContentEditor sourceprefs = new PdfContentEditor( docreader );
        PdfContentEditor destprefs = new PdfContentEditor( doccopy )) {
    destprefs.changeViewerPreference( sourceprefs.getViewerPreference() );
}

But after the “try” the documents docreader and doccopy are closed.
They shoul not since PdfContentEditor (like any class) should not close an instance that it has not itself created, so I considre this as a bug.
Please could you fix it or do you think this would break to much existing software ?

In any case would you please show me a workaround to get and set the viewer preferences of a document without closing the document ? Or using an other class ? I searched but did not find.
I ask because the documents instances are used also for other things and it is not a solution to close/open them several times in the processing.

Thank you very much

Hello
Thanks for your quick answer, I did a small eclipse project to reproduce : TestAspose.zip (47.8 KB)

Before running the test, please :

  • in the main() method, replace “D:/src/workspace/TestAspose/” with your own project directory
  • add aspose-pdf-22.2.jar in the /lib directory. (too big to put in the zip)
  • add Aspose.Total.Product.Family.lic in the root directory

The input “pdf/test.pdf” file is read by the program in the directory. It does the same with any pdf file I used.

One can check that the document is closed (in fact “disposed”) by reading the exception message, here is the message and callstack : callstack.png (11.1 KB)
class com.aspose.pdf.internal.ms.System.l8l: Cannot access a disposed object.
Object name: ‘Document’.

If I comment the line 49 “contenteditor.close();” there is no error.
But of course do not call close() would be bad practice.

Thank you very much for that.

In order to hope to have the fix earlier, perhaps should I add that we, Everteam, have a paid support for a global license ?
We cannot post message on the helpdesk because we reached the max 6 messages per year, but maybe I can send you a proof, for example by sending you our license in private?
