      1. NG case: deploy attached testappng.war and access to http://localhost:8080/testappng/xml. org.xml.sax.SAXParseException is generated in server.log.
      2. GOOD case: deploy testapp.war in a Maven project testapp.zip and access to http://localhost:8080/testapp/xml. No exceptions are generated. The only difference from testappng.war is that the workaround of META-INF/services and jboss-deployment-structure.xml.
      3. GOOD case: in the Maven project, execute mvn exec:java -Dexec.mainClass=com.example.XMLTest. No exceptions are generated because it uses JDK's implementaion.

      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.

      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.
