[Bug xml/31814] New: Element hasAttribute returns true even if element doesn't have specified attribute when document is validated (and maybe when it uses an entity resolver)

[fullung at gmail dot com]

I'm running the latest GNU Classpath from CVS as of 2007/05/04 10:00 GMT+2 with
IKVM.NET, also the latest from CVS.

Code to reproduce:

import java.io.ByteArrayInputStream;
import java.io.FileInputStream;
import java.io.IOException;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.xml.sax.EntityResolver;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;

public class HasAttributeBug {
        private static class MyEntityResolver implements EntityResolver {
                public InputSource resolveEntity(String publicId, String
systemId)
                                throws SAXException, IOException {
                        return new InputSource(new
FileInputStream("spring-beans-2.0.dtd"));
                }
        }

        private static void check(boolean validate) throws Exception {
                EntityResolver entityResolver = null;
                final String xml;
                if (validate) {
                        xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"
                                        + "<!DOCTYPE beans PUBLIC
\"-//SPRING//DTD BEAN 2.0//EN\"
\"http://www.springframework.org/dtd/spring-beans-2.0.dtd\";>"
                                        + "<beans><bean><property
name=\"name\"><value>value</value></property></bean></beans>";
                        entityResolver = new MyEntityResolver();
                } else {
                        xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"
                                        + "<beans><bean><property
name=\"name\"><value>value</value></property></bean></beans>";
                }
                DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
                factory.setNamespaceAware(false);
                factory.setValidating(validate);
                DocumentBuilder docBuilder = factory.newDocumentBuilder();
                docBuilder.setEntityResolver(entityResolver);
                InputSource inputSource = new InputSource(new
ByteArrayInputStream(xml.getBytes()));
                Document doc = docBuilder.parse(inputSource);
                Element ele = (Element)
doc.getElementsByTagName("property").item(0);
                boolean hasRefAttribute = ele.hasAttribute("ref");
                boolean hasValueAttribute = ele.hasAttribute("value");
                System.out.println(hasRefAttribute);
                System.out.println(hasValueAttribute);
        }

        public static void main(String[] args) throws Exception {
                check(false);
                check(true);
        }
}

On Sun JDK 1.5.0_10 this prints (as expected):

false
false
false
false

On GNU Classpath/IKVM.NET this prints:

false
false
true
true

i. e. with an entity resolver in place and validating set to true, hasAttribute
returns true when it should return false.
