Non-Compliant Code Examples

class MyClass {

    public void test() {
        SAXParser parser = SAXParserFactory.newInstance().newSAXParser();
        parser.parse(inputStream, customHandler);

        SAXParserFactory spf2 = SAXParserFactory.newInstance();
        SAXParser parser = spf2.newSAXParser();
    }
}

Compliant Code Examples

class MyClass {

    public void test() {
        SAXParserFactory spf = SAXParserFactory.newInstance();
        spf.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);
        SAXParser parser = spf.newSAXParser();
    }
