I fixed the HTMLFormatter.java file, problem was the String.replaceAll() method call which is supposed to accept a regular expression. The Strings that were used for the replaceAll had no regex ( private static final String templateVarTagName = "%tag-name%";) and probably confused the Java regex match with the percentage signs... however, changing it to String.replace() fixed the proble...
