------------------------------------------------------------------

We are hitting this issue too on upgrading from 2.0.5 to 2.0.12. To fix the issue one should
get the "Font"-Dictionary and check the existence there:

e.g.
{code}
    COSDictionary fontDict = (COSDictionary) defaultResources.getCOSObject().getDictionaryObject(COSName.FONT);
    if (!fontDict.containsKey("Helv"))
        {
            defaultResources.put(COSName.getPDFName("Helv"), PDType1Font.HELVETICA);
        }
{code}

What is missing for this to be fixed? 

I added a small git diff to fix the issue. I am unsure if my observed behaviour should be
another issue: if one calls getLastSignatureDictionary, the AcroFrom is populated with the
defaults.

For example:
{code}
            PDDocument pdfDocument = PDDocument.load(pdfBytes);
            pdfDocument.getLastSignatureDictionary();
{code}
This calls the verifyOrCreateDefaults() method.

> PDFBOX-3943: create /Helv and /ZaDb entries if they don't exist, regardless if /DR existed
or not

> was working ok in 2.0.7, in 2.0 branch

> verifyOrCreateDefaults():

> should be checking key in the font dictionary before calling defaultResources.put
