Error using dom4j module in JBoss EAP 6

Issue

• We are trying to use dom4j module available with JBoss EAP 6
• We are getting the following exception for the following statement

Document doc ...
Element element ...
DocumentSource docSource = new DocumentSource(element);

• Exception:

java.lang.IllegalAccessError: tried to access class org.dom4j.io.DocumentInputSource from class org.dom4j.io.DocumentSource

• The same code is working if we bundle dom4j-1.6.1.jar in our application (this is not from <module name="org.dom4j" slot="main" /> )
