-----------------------------------------------------------------
[~msahyoun] I've been able to fix the PDF by removing both annotation widgets
and adding one back in with the appearance I want and then using the duplicate
across pages feature in Acrobat DC. This resulted in a DA entry for the field
and none for the annotation widgets. I also now have an approach to unit test
all of our PDFs to check for this issue of non-matching DA entries. Thanks for
your help. I do believe itext has some code that allows annotation DA entries
to override the field DA, but I'm not positive. Their code is not the easiest
to read.

> PDFBox not recognizing Auto font size for PDField
> -------------------------------------------------
>
> Key: PDFBOX-3687
> URL: https://issues.apache.org/jira/browse/PDFBOX-3687
> Project: PDFBox
> Issue Type: Bug
> Components: AcroForm
> Affects Versions: 2.0.4
> Reporter: Scott Coldwell
> Attachments: SF1152.pdf, TestSF1152-LL.pdf
>
>
> See the attached file "SF1152.pdf" and locate the "Bureau" field. If you
> open this document in Acrobat the font size shows as Auto and functions as
> such in Acrobat/Acrobat Reader. However, PDFBox thinks the font size is set
> to 9. I confirmed this in both PDFDebugger and in our rendering code.
> The second attachment "TestSF1152-LL.pdf" shows the behavior from PDFBox not
> picking up the correct Auto font size. The value is truncated unless you
> click inside the field or delete the value and replace it.
> The following code shows the problem:
> {code}
> final PDDocument document =
> PDDocument.load(ClassLoader.getSystemResourceAsStream("SF1152.pdf"));
> final PDAcroForm form =
> document.getDocumentCatalog().getAcroForm();
> final PDTextField field = (PDTextField)form.getField("Bureau");
> final COSDictionary dict = field.getCOSObject();
> String defaultAppearance =
> ((COSString)dict.getDictionaryObject(COSName.DA)).getString();
> System.out.println(defaultAppearance);
> {code}
> results in:
> {code}
> /Helv 9 Tf 0 0 0.5 rg
> {code}
> If I manually set the font size to auto using:
> {code}
> dict.setString(COSName.DA, "/Helv 0 Tf 0 0 0.5 rg");
> {code}
> the PDF renders correctly.
> But we shouldn't have to manipulate font sizes in code when it's set
> correctly in the PDF.
