> An smiley face emoji, decimal code &#128513, can be parsed properly by JDK's implementation (loaded by {{com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl}}) but failed with WildFly's implementation (xercesImpl-2.11.0.SP5.jar) which throws {{org.xml.sax.SAXParseException}}.
> {code}
> org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 84; Character reference "&#55357" is an invalid XML character.

> This means a standalone Java application suddenly stops working on WildFly and need to be addressed. There is a workaround using files under {{META-INF/services}} and {{jboss-deployment-structure.xml}}. But the workaround is too mysterious for most of users. An out-of-the-box solution is expected.
