[Graal] emits unparseable XML into compile log

While using +LogCompilation tool with Graal, there is a org.xml.sax.SAXParseException because Graal emits unparseable XML with too much use of single-quote to wrap embedded object details as shown below. AFAICT so far C2 does not do this so it was never handled in the LogCompilation app code.
