      We can see NPE with the attached simple reproducer on JBoss EAP 7.4.18 and OpenJDK8:

      1. unzip reproducer-src.zip
      2. cd reproducer-src/webservice-server
      3. mvn package
      3. cp webservice-server.war JBOSS_EAP_7_4_18_HOME/standalone/deployments/
      4. Start JBoss EAP 7.4.18
      5. cd ../webservice-client
      6. mvn package exec:exec
      7. We can see NPE in server.log on server side

      NullPointerException is thrown when a client sends a request with an unmatched targetNameSpace to a WebService that meets the following conditions:

      • marked as Stateless Session Bean
      • has a HandlerChain
      @Stateless
//@WebService(targetNamespace ="http://com.redhat.gss.example.soap/") // correct targetNamespace
@WebService(targetNamespace ="http://com.redhat.gss.invalid/")        // invalid targetNamespace that is not matched with wsdl distributed to clients
@HandlerChain(file = "/META-INF/handlers.xml")
public class HelloService {...}

      It is more appropriate to throw an exception indicating the cause exception instead of NPE.

      If the Web Service is not stateless sesssion bean or no HandlerChain, the following exception will be thrown instead of NPE:
