Extract original exception in BasePDFTestCase.java. They are normally embedded in a TransformerException and sometimes additionally in a SAXException (depending on the JAXP implementation).

Restore validation for Base14 font check when PDF/A is active. Got lost when I refactored to generic structures in the PDF library.
