This doesn't work: SAXParserFactory factory = new WstxSAXParserFactory(); factory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true); SAXParser parser = factory.newSAXParser(); InputSource is = new InputSource(new FileInputStream(args[0])); parser.parse(is, new DefaultHandler()); It results in: Exception in thread "main" org.xml.sax.SAXNotRecognizedException: Feature 'http://javax.xml.XMLConstants/feature/secure-processing' not recognized As a result, it appears impossible to defend against "billion laughs"-style denial of service attacks, along the lines of: https://git.fedorahosted.org/cgit/secure-coding.git/tree/defensive-coding/src/data/XML-Parser-Internal_Entity_Exponential.xml https://git.fedorahosted.org/cgit/secure-coding.git/tree/defensive-coding/src/data/XML-Parser-Internal_Entity_Exponential_Attribute.xml
