------------------------------------------------------------------
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.
