> Key: PDFBOX-4477
> URL: https://issues.apache.org/jira/browse/PDFBOX-4477
> Project: PDFBox
> Issue Type: Bug
> Components: Crypto, Parsing
> Affects Versions: 2.0.14
> Reporter: Tilman Hausherr
> Assignee: Tilman Hausherr
> Priority: Major
> Labels: optimization
> Fix For: 2.0.15, 3.0.0 PDFBox
>
>
> As reported by [~slavago] in TIKA-2832. File is confidential but I have it.
> Initial findings:
> - File is AES256 encrypted with empty user password
> - File has about 1000 objects
> - File is a tagged PDF
> - HashMap in SecurityHandler grows to 100000?!
> - Using an IdentityHashMap speeds up the process dramatically (parsed in a
> few seconds), and it may also be a better solution that what was done in
> PDFBOX-4453
> Todo:
> - Read description of IdentityHashMap again
> - Find out why the HashMap grows so much. Could it be that identical objects
> are stored twice? Or does the file have many direct objects?
