Steps to Reproduce:

Hide

Cannot be reproduced without the original source code, which is too big and I cannot upload any part of it or of the WSDL file. I guess I could send privately the wsdl file if needed.
But I have tracked down what looks like a bug in the library jbossws-common-3.1.5.Final.jar, and I (think I) have fixed the problem in the jbossws-common-3.2.1 (master) one. With the fix the exception is not thrown any more. Please see fix in the description.

While deploying a EAR application, which contains a WAR which is trying to register a web service, I get the follwing exception:

I wasted 3 days trying to find a solution thinking that the problem was in my dependencies with xerces or any other xml resolver.
Then I decided to checkout the code near the root cause:

Caused by: java.lang.NullPointerException

	at __redirected.__RedirectedUtils.findProviderClassNames(__RedirectedUtils.java:147)

and I think I have fixed a bug in jbossws-common-3.1.5.
I have downloaded the latest version of jbossws-common-master from github (with which the problem was still showing).

Then I fixed the class org/jboss/ws/common/utils/DelegateClassLoader.java changing this:

   /** {@inheritDoc} */
   @Override
   public InputStream getResourceAsStream(final String name)
   {
      InputStream is = parent.getResourceAsStream(name);
      return (is == null) ? delegate.getResourceAsStream(name) : is;
   }

to this:

   /** {@inheritDoc} */
   @Override
   public InputStream getResourceAsStream(final String name)
   {
      InputStream is = null;
      if (parent != null)
      {
        is = parent.getResourceAsStream(name);
      }
      return (is == null) ? delegate.getResourceAsStream(name) : is;
   }

and then built again the jbossws-common jar and replaced the (suspected) faulty one under the WildFly modules. With the new jar the webservice can be registered.
