  The method org.w3c.dom.Document.normalizeDocument() throws NullPointerException
if a simple xml document is validated by XML Schema and 'datatype-normalization'
is set to true.

The method description does not specify any exception.

This bug affects new tests in JCK 1.5 (not integrated yet)
   api/org_w3c/dom/DOMConfiguration/index.html#Params[DatatypeNormalization001]

The bug is found in jdk1.5.0/beta/b30.

To reproduce the bug place test.java, test.xml and test.xsd to your current directory,
then compile and run test.java as shown in the log below:
------------------------------ test.java
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.DOMConfiguration;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.XMLConstants;

class test {

    static final String SCHEMA_LANGUAGE
        = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
    static final String SCHEMA_SOURCE
        = "http://java.sun.com/xml/jaxp/properties/schemaSource";

    static Document loadDocument(String schemaFile, String instanceFile)
                                        throws Exception {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        if (schemaFile != null) {
            dbf.setNamespaceAware(true);
            dbf.setValidating(true);
            dbf.setAttribute(SCHEMA_LANGUAGE
                , XMLConstants.W3C_XML_SCHEMA_NS_URI);
            dbf.setAttribute(SCHEMA_SOURCE, schemaFile);
        }
        return dbf.newDocumentBuilder().parse(instanceFile);
    }

    public static void main(String [] args) throws Exception {
        Document doc = loadDocument("test.xsd", "test.xml");
        DOMConfiguration config = doc.getDomConfig();
        config.setParameter("validate", Boolean.TRUE);
        Element root = doc.getDocumentElement();

        System.out.println("normalizing with 'datatype-normalization' set to "
            + config.getParameter("datatype-normalization") + " ...");
        doc.normalizeDocument();
        System.out.println("OK");

        config.setParameter("datatype-normalization", Boolean.TRUE);

        System.out.println("normalizing with 'datatype-normalization' set to "
            + config.getParameter("datatype-normalization") + " ...");
        doc.normalizeDocument();
        System.out.println("OK");
    }
}
