Embedded FOP 2.3 - SVG not working when transforming from any source but files

Hi,

I experienced a weird behaviour when embedding SVG and transform it with FOP 2.3 when using another input source than files

The part that deals with the transformation look like this:

One time init:
kTransFactory = new net.sf.saxon.TransformerFactoryImpl();
kFopFactory = FopFactory.newInstance(new File(kConfigPath));


Transformation:
Transformer transformer = kTransFactory.newTransformer(xslt);
			transformer.setErrorListener(errorListener);
FOUserAgent foUserAgent = kFopFactory.newFOUserAgent();
Fop fop = kFopFactory.newFop(type, foUserAgent, result);
Result res = new SAXResult(fop.getDefaultHandler());
transformer.transform(xml, res);

xslt and xml are StreamSource objects.

If I get the data from a file there is no problem embedding svg images in
the pdf.
I.e.
StreamSource xslt = new StreamSource(new File("path to file"));
StreamSource xml = new StreamSource(new File("path to file"));
produces the correct output and embeds the SVG image correctly into the
pdf/ps.

On the other hand, if I get the data via a socket and use byte[] as input,
like so:
StreamSource xslt = new StreamSource(new ByteArrayInputStream(xsltData));
StreamSource xml = new StreamSource(new ByteArrayInputStream(xmlData));

I get no SVG images in the pdf/ps output.
Log output with stacktrace when generating pdf/ps:

The PDF will still get generated, but all svg-images are missing.

Is there anything I do wrong? (The apache-fop homepage mentions using a ByteArrayInputStream, however converting the byte[] to a String and using a StreamReader I get the exact same result.. no SVG in PDF/PS)
I would really like to avoid saving the received byte[] data into a file to get a correct output from FOP/Batik

Thanks!
