Michael Klink commented on PDFBOX-5451:
---------------------------------------
Please consider documenting this in the JavaDocs and probably also in the 3.0.0
migration guide.
People used to the cloning may re-use their byte arrays...
> Avoid copying byte array for COSString

> Project: PDFBox
> Issue Type: Improvement
> Components: Parsing
> Affects Versions: 3.0.0 PDFBox
> Reporter: Andreas Lehmkühler
> Assignee: Andreas Lehmkühler
> Priority: Major
> Fix For: 3.0.0 PDFBox

>
> When creating a COSString the given byte array is cloned. As in most cases
> the array is just an intermediate object we should remove that to reduce the
> memory footprint.
> Furthermore the {{getBytes}} returns the internal byte array so that I don't
> see any reason not to use the given byte array itself instead of cloning it
