[memo] this parser does not support specification null version null digester

java.lang.UnsupportedOperationException: This parser does not support specification "null" version "null"
at javax.xml.parsers.SAXParserFactory.setXIncludeAware(SAXParserFactory.java:448)
at org.apache.commons.digester.Digester.getFactory(Digester.java:534)

Update your xercesImpl.jar!!! old xercesImpl.jar can not handle setXIncludeAware method.
2.9.1 helps you.

Thank you Coding in Color!!!
