--------------------------------------------
I've just realized that the code in the trunk is different. We should consider
some similar solution when working PDFBOX-2515.
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
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.
