createDocument() throws DOMException if all parameters are null

Name: eaR10174 Date: 08/27/2003


  The method DOMImplementation.createDocument() throws DOMException with the error code
INVALID_CHARACTER_ERR in case when the all parameters are null (see test.java below).
According to the method javadoc:
  
  Returns:
    A new Document object with its document element. If the NamespaceURI, qualifiedName,
    and doctype are null, the returned Document is empty with no document element.

the method should return a Document object.

  The bug appears in jdk1.5.0beta-b16 and affects a new JCK1.5 test:

     api/org_w3c/dom/DOMImplementation/index.html#CreateDocument[CreateDocument012]

------------------------------------test.java-----------------------------
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.DOMImplementation;
import org.w3c.dom.Document;
import org.w3c.dom.DOMException;

public class test {

    public static void main(String argv[]) {
        new test().run();
    }
    
    public void run() {
        Document document = null;
        try {
            document = DocumentBuilderFactory.newInstance()
                       .newDocumentBuilder().newDocument();
        } catch (Exception e) {
            System.out.println("Can't create an empty document.");
            return;
        }
    
        DOMImplementation implementation = document.getImplementation();

        try {
            document = implementation.createDocument(null, null, null);
        
            System.out.println("Method does not throw an exception.");
        } catch (DOMException e) {
            if (e.code == DOMException.NAMESPACE_ERR) {
                System.out.println("OK");
            } else {
                System.out.println("Unexpected error code of exception: " + e );
            }
        }
    }
}
