Did setIgnoringElementContentWhitespace quit working in 1.6?! Is it a bug?

Question

I'm desperate for some help here. I know it looks like a long post but it really isn't. Basically, I have some code that works find in 1.5 but now is broken in 1.6. Here is the code (error handling, etc. has been removed):
File schemaFile = new File("test.xsd");
// Now attempt to load up the schema
Schema schema = null;
SchemaFactory schFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
schema = schFactory.newSchema(schemaFile);
File xmlFile = new File("test.xml");
// Set the options on the DocumentFactory to remove comments, remove whitespace
// and validate against the schema.
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
docFactory.setIgnoringComments(true);
docFactory.setIgnoringElementContentWhitespace(true);
docFactory.setSchema(schema);
DocumentBuilder parser = docFactory.newDocumentBuilder();
Document xmlDoc = parser.parse(xmlFile);Here is the sample XML:
<Person>
        <FirstName>Doofus</FirstName><!-- MONKEY -->
        <LastName>McGee</LastName>
</Person>Here is the sample schema:
<xsd:schema xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
  <xsd:element name='Person' type='PersonType'/>
  <xsd:complexType name='PersonType'>
                <xsd:sequence>
                        <xsd:element name='FirstName' type='xsd:string'/>
                        <xsd:element name='LastName' type='xsd:string'/>
                </xsd:sequence>
        </xsd:complexType>
</xsd:schema>In 1.5, it correctly removes the extraneous whitespace nodes and in 1.6 it does not. Java 1.5 gives me:
NODE: Person   TYPE: element   VALUE:
  NODE: FirstName   TYPE: element   VALUE:
    NODE: #text   TYPE: text   VALUE: Doofus
  NODE: LastName   TYPE: element   VALUE:
    NODE: #text   TYPE: text   VALUE: McGeeJava 1.6 gives me:
NODE: Person   TYPE: element   VALUE:
  NODE: #text   TYPE: text   VALUE:
  NODE: FirstName   TYPE: element   VALUE:
    NODE: #text   TYPE: text   VALUE: Doofus
  NODE: #text   TYPE: text   VALUE:
  NODE: LastName   TYPE: element   VALUE:
    NODE: #text   TYPE: text   VALUE: McGee
  NODE: #text   TYPE: text   VALUE:Can anyone tell me why this is happening? Both versions correctly remove the comments but only 1.5 removes the whitespace. This definitely seems like a bug to me.

Thanks for the suggestion but I don't think it is gonna work. When I used both setSchema() and setValidating(), it was not happy. So I removed the setSchema() call and had the XML file reference the Schema (just recreated the documents from http://www.w3schools.com/schema/schema_howto.asp) and here is what I get now (note that I get the same thing in 1.5 as well):
Error: URI=file:/home/mcnally/test.xml Line=5: Document root element "note", must match DOCTYPE root "null".
Error: URI=file:/home/mcnally/test.xml Line=5: Document is invalid: no grammar found.
NODE: note   TYPE: element   VALUE:
  NODE: #text   TYPE: text   VALUE:
  NODE: to   TYPE: element   VALUE:
    NODE: #text   TYPE: text   VALUE: Tove
  NODE: #text   TYPE: text   VALUE:
  NODE: from   TYPE: element   VALUE:
    NODE: #text   TYPE: text   VALUE: Jani
  NODE: #text   TYPE: text   VALUE:
  NODE: heading   TYPE: element   VALUE:
    NODE: #text   TYPE: text   VALUE: Reminder
  NODE: #text   TYPE: text   VALUE:
  NODE: body   TYPE: element   VALUE:
    NODE: #text   TYPE: text   VALUE: blah blah blah
  NODE: #text   TYPE: text   VALUE:I ignored setValidating at first because of the API says, "To use modern schema languages such as W3C XML Schema or RELAX NG instead of DTD, you can configure your parser to be a non-validating parser by leaving the setValidating(boolean) method false, then use the setSchema(Schema) method to associate a schema to a parser." Combined with the statement you pulled from the setIgnoring...() documentation it almost seems to indicate that it cannot pull out the whitespace if you use anything other than a DTD. However, this seems dumb to me and it definitely works in 1.5. In any case, I don't know what is going on but I'm convinced this is a bug.
One thing I did notice is that the call to setIgnoringContentElementWhitespace() toggles an underlying feature that doesn't exist in 1.5 (specifically "http://apache.org/xml/features/dom/include-ignorable-whitespace"). I can set that feature in 1.6 and it accepts it (still doesn't work) but in 1.5 it says it is an unrecognized feature. Does anyone know what feature the API call toggled in 1.5 (if any)?
