PrettyPrint not working as expected about citrus

Don't forget to check the spaces in
builder.append(" <message>Hello</message>");
3 or 4 spaces?

This is because we upgraded our Xerces dependency and in the new version Xerces XML serializer creates this kind of output. I checked on properties and settings for the XML serializer, but did not find a proper solution to get the old format.

Hello Christoph,

A solution could be to use in the utility class the JDK instead of the external Xerces.
Set the system property of the DOMImplementationRegistry for this class and it will make use of the internal JDK Xerces.

    static {
        System.setProperty(DOMImplementationRegistry.PROPERTY,"com.sun.org.apache.xerces.internal.dom.DOMImplementationSourceImpl");
        try {
            registry = DOMImplementationRegistry.newInstance();
            domImpl = (DOMImplementationLS) registry.getDOMImplementation("LS");
        } catch (Exception e) {
            throw new CitrusRuntimeException(e);
        }
    }

I have forked the project and changed the test case also added the property, it seems to work fine now. But I'm new to git and github, and I don't know how to push the changeset to you.
