--------------------------------------

Thanks for the feedback! 

 

Glad I wasn't far from the actual fix :) 

 

> Regression on COSWriter in PDFBox 2.0.15
> ----------------------------------------
>
>                 Key: PDFBOX-4552
>                 URL: https://issues.apache.org/jira/browse/PDFBOX-4552
>             Project: PDFBox
>          Issue Type: Bug
>          Components: Writing
>    Affects Versions: 2.0.15
>            Reporter: Maxime Veron
>            Priority: Blocker
>              Labels: regression
>
> In method _doWriteTrailer_ an unsafe setter is called on 
> _getItem(COSName.ID).setDirect(true)_.
>  
> It was not done in PDFBox 2.0.14. This causes NPEs. 
> My quick and easy fix to restore PDFBox 2.0.14 behavior : 
>  
> {code:java}
> COSArray id = ((COSArray) trailer.getItem(COSName.ID));
> if (id != null) 
> {
>     id.setDirect(true);
> }
> {code}
> Best regards,
> M.Véron
