Using transformer inside transformer fails on JDK 25, works on older JDKs (11,17,21)

public class test {

    public static void main(String[] args) throws Exception {

        Transformer transformer = factory.newTransformer();
        Source src = new StreamSource(new ByteArrayInputStream("<a/>".getBytes()));
        Result res = new SAXResult(new DefaultHandler() {

                            = (SAXTransformerFactory) SAXTransformerFactory.newInstance();

                } catch (Exception e) {
                    throw new RuntimeException(e);
                }
            }
        });
        transformer.transform(src, res);
    }
}
