     The following method of the default org.w3c.dom.Document interface implementation

Node importNode(Node importedNode, boolean deep)

throws NullPointerException when a DocumentType node is imported.

The documentation of the method reads:

"
The following list describes the specifics for each type of node.
...
DOCUMENT_TYPE_NODE
    DocumentType nodes cannot be imported.
...
Throws:
    DOMException - NOT_SUPPORTED_ERR: Raised if the type of node being imported
                   is not supported.
"

So, in the test (see below) NOT_SUPPORTED_ERR DOMException is expected
instead of NullPointerException.

This bug affects new test in JCK 1.5
    api/org_w3c/dom/Document/index.html#ImportNode[ImportNode005]

The bug is found in jdk1.5.0/beta/b51 and is not reproducible in jdk1.5.0/beta/b50.

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

class test {
    public static void main(String [] args) throws Exception {
        DocumentBuilder docBuilder = DocumentBuilderFactory.newInstance().
                                 newDocumentBuilder();
        Document document1 = docBuilder.newDocument();
        Document document2 = docBuilder.newDocument();

        DocumentType docType = document1.getImplementation()
                              .createDocumentType("root", null, null);

        try {
            document2.importNode(docType, false);
            System.out.println("Failed: document type node imported,"
                             + " no exception is thrown.");
        } catch (DOMException e) {
            int code = ((DOMException)e).code;
            if (DOMException.NOT_SUPPORTED_ERR == code) {
                System.out.println("Passed.");
            } else {
                System.out.println("Failed: Unexpected error code "
                                 + code);
            }
        }
    }
}
