    Resolution: Cannot Reproduce

[~jasonmackin] I've tried with 2.0.0, 2.0.1, 2.0.2, 2.0.4 and trunk and can't reproduce the issue. If that is still valid please reopen together with a small test to reproduce the issue.

> When trying to exportFDF() in PDAcroForm.java, there is a ClassCastException thrown when addFieldAndChilden(PDFieldTreeNode docField, List<FDFField> fdfFields) is called and the docField is a PDRadioButton that has kids and one is a PDWidget.
> PDRadioButton.getKids() says:
> "This will get all the kids of this field. The values in the list will either be PDWidget or PDField. Normally they will be PDWidget objects unless this is a non-terminal field and they will be child PDField objects."
> But when kids are returned in the addFieldAndChilden method and one is a PDWidget (PDAnnotationWidget in my case), it tries to cast it as a PDFieldTreeNode and throws the exception.
