String index out of range -35421

[Bill Gates]

I'm getting a weird behavior using Xalan 2.0.1 and the transform
method.  I'm not sure if it's just my lack of understanding of what's
happening or a real issue.  I presumed that this would work.

(This isn't the exact code because it's spread out but a best display of
the snippets I'm using with Xalan.)

I have a ControlledParser class which is essentially a subclass of
DomParser with the setDeferred expansion to false by default.  This is
the behavior we need.

I get an instance of the parser and call
parser.parse(new InputSource(new StringReader(xmlString)));
Then I get a DOMSource with new DOMSource(parser.getDocument())

I get my xml source and xsl source the same way.  Then I do the basics:

DOMResult domResult = new DOMResult();
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(xslSource);
transformer.transform(xmlSource, domResult);

This all seems pretty rudimentary to me.  It seems to work until the
point where I have an xmlSource file of greater than 76K (roughly).
Then I start getting the String index out of range errors during the
transform call.

I can fix this by instead doing:

            DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
            factory.setNamespaceAware(true);
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document xmlDoc = builder.parse(new InputSource(
                new StringReader(xml)));
            DOMSource xmlSource = new DOMSource(xmlDoc);

To get the xmlSource and then doing the same transform but I'm not sure
why that is.  Could somebody explain to me the difference?  I would have
though that I could pass any DOMSource to the transform and it would
work but that doesn't seem to be the case.  It's apparent to me I'm
missing something basic.

   Thanks,
