javax SchemaFactory disable access to external entities not recognized

I am using javax SchemaFactory to parse an XML file. I get a SonarLint warning "Disable access to external entities in XML parsing.". The warning goes away when adding two properties "ACCESS_EXTERNAL_DTD" and "ACCESS_EXTERNAL_SCHEMA". However, when parsing something I get the runtime error "Feature 'http://javax.xml.XMLConstants/property/accessExternalDTD' is not recognized.". Why is it not recognized and how to fix this? My code:

import javax.xml.XMLConstants;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;

public class MinimalExample {

    public static void main(String[] args) {
        SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        factory.setProperty(XMLConstants.ACCESS_EXTERNAL_DTD, "");
        factory.setProperty(XMLConstants.ACCESS_EXTERNAL_SCHEMA, "");
    }
}

I don't understand why those properties are not recognized and don't know what else to try.
