Tilman Hausherr resolved PDFBOX-3363.
-------------------------------------
    Resolution: Fixed

I did an implementation similar to what is done in PDDocument. I remember that once (but don't remember why), the cached stream was accessed after parsing so we shouldn't close it too soon.

>    I'm trying to add a signature to a PDF using PDFBOX 2.0.1. During the
> process, a tmp file (e.g: tmpPDFBoxXXX.pdf) is stored inside the /tmp
> directory (RehHat server). This file is not deleted after completion.
> After some checks, it seems that the object responsible of the file
> creation is  "RandomAccessBufferedFileInputStream(InputStream is)". This
> object is used by the PDFParser object which doesn't close the stream
> after
> completion.

>  For your information I found a workaround to avoid the problem of tmp file
> deletion. In the SignatureOptions object, I modified the method  *public
> void setVisualSignature(InputStream is)  *with the following content :
>       RandomAccessBufferedFileInputStream tmp=new
> RandomAccessBufferedFileInputStream(is); --> NEW LINE
>          PDFParser parser = new PDFParser(tmp);  --> NEW LINE
>          parser.parse();
>          visualSignature = parser.getDocument();
>          tmp.close();  --> NEW LINE
> Tmp files are well deleted and all unit tests passed without error on the
> pdfbox maven project.
