Server runs for days without any problem but this morning XSLT isn't working with this error:

code in question is

StreamSource xml = new StreamSource(new StringReader(fopjuice));
FopFactory fopFactory = FopFactory.newInstance(new File(".").toURI());
ByteArrayOutputStream out = new ByteArrayOutputStream();
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, out);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
Result res = new SAXResult(fop.getDefaultHandler());
transformer.transform(xml, res); // <-- BLOWS UP HERE
return out.toByteArray();

i hadn't reloaded any resources since startup
