You must have some code in those multiple layer of your applcation that 
must be eating the Exception (do a try/catch and not print/, log or 
re/throw exception)

try this


SAXSVGDocumentFactory f = null;
try {
	f = new SAXSVGDocumentFactory(parser);
} catch (Throwable e) {
	// Notice that it is Throwable and not Exception,
	// it catches Error too
	e.printStackTrace();
	throw e;
}
