John Hewson commented on PDFBOX-2596:
-------------------------------------
I guess you didn't read the JavaDoc:
{code}
/**
* This is the in-memory representation of the PDF document. You need to call
* close() on this object when you are done using it!!
* <p>
* This class implements the {@link Pageable} interface, but since PDFBox
* version 1.3.0 you should be using the {@link PDPageable} adapter instead
* (see <a
href="https://issues.apache.org/jira/browse/PDFBOX-788";>PDFBOX-788</a>).
*
* @author <a href="mailto:[email protected]";>Ben Litchfield</a>
* @version $Revision: 1.47 $
*/
public class PDDocument implements Pageable, Closeable
{code}
We also implement Closeable, which is about as clear as you can get.
> NullPointerException in RandomAccessFileInputStream
> ---------------------------------------------------
>
> Key: PDFBOX-2596
> URL: https://issues.apache.org/jira/browse/PDFBOX-2596
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 1.8.8
> Reporter: John Roche
>
> Line 94 contains a synchronized(file) that throws a NullPointerException
> under some strange circumstances that I haven't been able to fully identify
> yet. I have downloaded the 1.8.8 source and the fix I used is simply to add
> "&& file != null" to the previous if statement.
> I can reproduce this bug with live user data, but I haven't been able to with
> test data yet. It happens when I try to create a pdf with 36 pages that have
> an image, some drawn coloured boxes and some text, on each page. If I remove
> some of the pages before I call save(File) it doesn't happen - depending on
> which pages I remove it can be ok with up to 26 pages, or break with fewer.
> Quite strange. I suspect it's to do with the size of the data as opposed to
> the number of pages.
> I will continue to investigate, since there seems to be some underlying
> issue, but for now I guess the null protection should be ok to add?
> Thanks,
> John
