> Preserve indirect object reference when copying resources

>                 Key: PDFBOX-5254
>                 URL: https://issues.apache.org/jira/browse/PDFBOX-5254
>             Project: PDFBox
>          Issue Type: Improvement
>          Components: AcroForm
>    Affects Versions: 2.0.24, 3.0.0 PDFBox
>            Reporter: Andreas Lehmkühler
>            Assignee: Andreas Lehmkühler
>            Priority: Major
>             Fix For: 2.0.25, 3.0.0 PDFBox

>
> In {{AppearanceGeneratorHelper.validateAndEnsureAcroFormResources()}} font resources are copied by simply reassigning the PDFont from the default resources. This removes any indirect object references which leads to doubled objects when writing the pdf.
> The issue revealed another issue with the COSWriter when lfatting the pdf from PDFBOX-4889 without compression.
