Hello everyone,

I am migrating some web systems that use third party libraries. One of them use its own DocumentBuilderFactory class.

I created a module for the libraries, and the classes in that module are being accessed fine by the applications.

When I try to use DocumentBuilderFactory it gives a classCastException.

I tryed to exclude DocumentBuilderFactory from javaee.api with both ways indicated at this post   https://community.jboss.org/message/637818#637818#637818 https://community.jboss.org/message/637818#637818.

Neither worked and I still keep recieving the error: 
java.lang.ClassCastException: __redirected.__DocumentBuilderFactory cannot be cast to javax.xml.parsers.DocumentBuilderFactory

Is it because __redirected.__DocumentBuilderFactory is not on javax.xml.parsers? so I guess the configuration to exclude <exclude path="javax/xml/parsers" /> would not work, right?
If so, how can I resolve this issue? Where is __redirect.__DocumentBuilderFactory? Why is Jboss trying to use it instead of my own class.

Thanks in advance and follows the 2 configurations I had tryed according to the answer in that post: (I also tryed many variations trying to exclude javax/xml/parsers from javaee.api)
