> OutOfMemoryError in PDExtendedGraphicsState#getLineDashPattern
> --------------------------------------------------------------
>
> Key: PDFBOX-4162
> URL: https://issues.apache.org/jira/browse/PDFBOX-4162
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.8
> Reporter: Andreas Hubold
> Assignee: Andreas Lehmkühler
> Priority: Critical
> Fix For: 2.0.10, 3.0.0 PDFBox
>
>
> I'm getting an OutOfMemoryError from PDFBox when parsing a certain PDF using
> the Apache Tika App v 1.17 - which uses PDFBox 2.0.8 internally. This is
> reproducible even with 8GB heap.
>
> The OutOfMemoryError happens in
> org.apache.pdfbox.pdmodel.graphics.state.PDExtendedGraphicsState#getLineDashPattern,
> which contains this piece of suspicious code:
> {code:java}
> COSArray dp = (COSArray) dict.getDictionaryObject( COSName.D );
> if( dp != null )
> {
> COSArray array = new COSArray();
> dp.addAll(dp);
> {code}
> The last line is wrong. It appends all elements from 'dp' to 'dp' again,
> effectively duplicating the elements in the list. Maybe the intention was to
> add it to the created array instead.
>
> Stacktrace:
> {noformat}
