Indeed, that seems to be the case. It magically worked after replacing the following line: http://codehaus-plexus.github.io/plexus-utils/xref/org/codehaus/plexus/util/xml/PrettyPrintXMLWriter.html#L307
with this: String element = elementStack.removeLast(); write( "</" + element + ">" ); I will soon create the issue and PR.
