-------------------------------------
Did a quick test with [^programWinter2015_20210103_091853-sig_LTV.pdf] 35MB
when doing -Xmx70m , the signature works
with -Xmx50m

> OutOfMemory while signing large documents
> -----------------------------------------
>
> Key: PDFBOX-2512
> URL: https://issues.apache.org/jira/browse/PDFBOX-2512
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing, Signing
> Affects Versions: 1.8.7
> Reporter: Thomas Chojecki
> Assignee: Thomas Chojecki
> Priority: Major
> Fix For: 1.8.8
>
> Attachments: keystore.p12
>
>
> While working with large documents, we found some memory issues.
> 1. The method close() in the COSDocument, clones the objectpool and does not
> clean it properly. The cloning in getObjects() cause a OutOfMemory exception.
> 2.The COSWriter copy the whole pdf into the memory for signing and does not
> use BufferedInputStream for the FileInputStream which also has a big
> performance impact. (PDFBOX-1798)
> 3. The cloning of COSStreams cause a OutOfMemory exception
> I used the CreateSignature example with a about 150 MB big document from here:
> https://cdn-reichelt.de/bilder/downloads/reichelt_01-2015_DE_B_HQ.pdf
> Additionaly I add a RandomAccessFile to the PDDocument.load in the
> CreateSignature class.
> PDDocument doc = PDDocument.load(document,new RandomAccessFile(new
> File("d:\\temp.bin"), "rw")); (this prevent the OOM for the third case)
> The use of a BuffedInputStream in case two, will increase the signing speed
> from more than 5 minutes to less than 1 minute.
