> Key: PDFBOX-5068
> URL: https://issues.apache.org/jira/browse/PDFBOX-5068
> Project: PDFBox
> Issue Type: Improvement
> Components: Signing
> Affects Versions: 2.0.23
> Reporter: Ralf Hauser
> Priority: Major
> Attachments: RandomAccessReadBufferDiag.java, minimum.pdf
>
>
> Continuation of PDFBOX-2512
>
> in COSWriter.prepareIncrement(), for the test case
> cosDoc.getXrefTable().keySet() has size 5925. For each of thes keys,
> cosDoc.getObjectFromPool() gets an object that is not just referencing some
> part of the input document, but duplicates it (which is unavoidable in the
> case where they are decompressed with FlateFilter - albeit this could
> possibly be done "lazy")
> -Xmx20m 746/5925
> -Xmx25m 1615/5925
> -Xmx30m 2800/5925
> -Xmx40m 3872/5925
> -Xmx55m 5773/5925
> With 60m, it gets them all, but dies later with less telling
> java.lang.OutOfMemoryError: GC overhead limit exceeded
>
> This assumes the patch of PDFBOX-5067 already in place - or using
> CreateVisibleSignature2.java as starting point
