     The method Node.replaceChild(Node newChild, Node oldChild) throws
java.lang.ClassCastException when the oldChild parameter is a DocumentType node.

The method is specified to throw DOMException, but the ClassCastException
is not an instance of that. So it is a bug.

In the test (see below) HIERARCHY_REQUEST_ERR is expected according to the
last case of following wording:
"
Throws:
DOMException - HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does
not allow children of the type of the newChild node, or if the node to put in is
one of this node's ancestors or this node itself, or if this node is of type
Document and the result of the replacement operation would add a second DocumentType
or Element on the Document node.
"

This bug affects new test in JCK 1.5 (not integrated yet)
    api/org_w3c/dom/Node/index.html#ReplaceChild[ReplaceChild010]

The bug is found in jdk1.5.0/beta/b41.

To reproduce the bug compile and run test.java as shown in the log below:
------------------------------------------ test.java
import java.io.StringReader;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.DOMException;
import org.w3c.dom.Document;
import org.w3c.dom.DocumentType;
import org.w3c.dom.Element;
import org.xml.sax.InputSource;

class test {

     static final String docText = "<?xml version=\"1.0\" ?>"
                 + "<!DOCTYPE root ["
                 + "ELEMENT root ANY"
                 + "ENTITY ent \"foo\""
                 + "NOTATION not PUBLIC \"http://test/test.txt\""
                 + "]>"
                 + "<root/>";

     public static void main(String argv[]) throws Exception {
         Document document = null;
         InputSource inSource = new InputSource(new StringReader(docText));
         document = DocumentBuilderFactory.newInstance()
                  .newDocumentBuilder().parse(inSource);

         Element node = document.createElement("ANewElement");
         DocumentType docType = document.getDoctype();

         try {
             document.replaceChild(node, docType);

             System.out.println("Failed: "
                          + "replaceChild does not throw a DOMException");
         } catch (DOMException e) {
             if (e.code == DOMException.HIERARCHY_REQUEST_ERR
              || e.code == DOMException.NOT_SUPPORTED_ERR) {
                 System.out.println("Passed.");
             } else {
                 System.out.println("Failed: "
                                  + "Unexpected error code " + e.code);
             }
         }
     }
}

The test.java should be corrected to define docText variable as follows:
------------------------------------------------------------------------
     static final String docText = "<?xml version=\"1.0\" ?>"
                 + "<!DOCTYPE root ["
                 + "<!ELEMENT root ANY>"
                 + "<!ENTITY ent \"foo\">"
                 + "<!NOTATION not PUBLIC \"http://test/test.txt\">"
                 + "]>"
                 + "<root/>";
