I must have been very tired when looking for the attachment.

Maybe, but it is way more complex than it should have to be.
Anyway, I get two failures because of:
junit.framework.AssertionFailedError
caused by
javax.xml.transform.TransformerException
caused by
java.net.UnknownHostException
And it is little wonder as your stylesheet PI misses a valid URI:
<?xml-stylesheet type="text/xsl"
href="file://${basedir}/target/test-classes/transcript.xsl"?>
Corrected this to:
http://localhost/g/xml-util/target/test-classes/transcript.xsl
Now:
junit.framework.AssertionFailedError
caused by
java.io.IOException: Stream closed
Okay, the error is in reading the PI from the StreamSource by calling
getAssociatedStylesheet(), and then trying to read again from the same
StreamSource by calling transform(). Streams are to be used once only.
Fixing this in your program is cumbersome, because you have one big
method with parameters of type Object which you then cast to whatever
you need based on what instanceof tells you.
public static String xslTransformation(
final Object xml,
final Object xsl,
final Map parameters )
What's wrong with using polymorphism instead? It's vastly superior.
Also, please consider providing simple test cases. You'd have discovered
this error yourself if you had taken the time to build a simple test
case without so many complicating ingredients. It bears repeating here
that simplifying is a basic problem solving technique.
Best,
