    Description

      There appears to be a regression in the feature support in SAXParser and SAXParserFactory in Java 22 early access builds.

      Prior to recent early access builds, the following SaxParserTest class always printed "true" twice.

      import javax.xml.parsers.SAXParser;
      import javax.xml.parsers.SAXParserFactory;

      import org.xml.sax.XMLReader;

      public class SaxParserTest {

      public static void main(String[] args) throws Exception {
      SAXParserFactory parserFactory = SAXParserFactory.newInstance();
      parserFactory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
      System.out.println(parserFactory.getFeature("http://apache.org/xml/features/disallow-doctype-decl"));

      SAXParser saxParser = parserFactory.newSAXParser();
      XMLReader reader = saxParser.getXMLReader();
      System.out.println(reader.getFeature("http://apache.org/xml/features/disallow-doctype-decl"));
      }

      }

      Tested against Java 17, 21, and 22 EA.
