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);
