Subject: [PATCH] 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.
