Is it valid to be able to pass Null to Document.createCDATASection()
or is this a bug?

Subject: passing null to createCDATASection
I'm using 2.2.1.
I was building a Document and a passed a null to the call createCDATASection
(this did not fail which surprised me..)
when I tried to transform (basically creating a string of the dom)
public static String toString(Node node)
{
StringWriter sw = new StringWriter();
try
{
Transformer serializer =
TransformerFactory.newInstance().newTransformer();
serializer.transform(new DOMSource(node), new StreamResult(sw));
}
catch (TransformerException e)
{
DOMException de = new DOMException(DOMException.SYNTAX_ERR, "failed to
translate DOM");
de.initCause(e);
throw de;
}
return sw.toString();
}
it I got the following
java.lang.NullPointerException

org.apache.xml.utils.TreeWalker.dispatachChars(TreeWalker.java:292)

it also failed for xslt transformation

I would expect to get a NullPointerException when I created the
CDATASection.
