Why the code XPathFactory.newInstance().newXPath() throws NullPointerException in EAP6

Issue

• Application is packaged within a war file, tested as working on tomcat 7. The Web Application contains the camel jar "WEB-INF/lib/camel-core-2.12.1.jar" inside it.

• The application is trying to run camel xpath on eap6, always throws a NullPointerException when trying to execute the following code:

XPath xPathEvaluator = XPathFactory.newInstance().newXPath();

• The Exception encountered at the execution of above code is as following:
