How to exclude specific classes / packages from dependencies in JBoss EAP 7/6

Issue

• We are installing a war file. The war package needs to load a class from a jar in WEB-INF/lib instead of the one provided by the JBoss module.
• For example, we would like to force JBoss to not load classes from com/sun/org/apache/xml/internal/security/transforms/implementations which is under the sun.jdk module by excluding it in WEB-INF/jboss-deployment-structure.xml and instead load this particular class from WAR provided WEB-INF/lib/xmlsec.jar.
• Our web deployment MyWeb.war has dependency on another deployment AnotherDeployment.ear(AnotherDeployment.jar), how to declare dependency on AnotherDeployment.ear(AnotherDeployment.jar) , but exclude some classes / packages from it ?
• I am trying to add <exclude path="com/abc"/> in my jboss-deployment-structure.xml in MyWeb.war, to exclude class com.abc.util.UtilClass from another dependency deployment, but that doesn't work.
• How do I setup class exclusion or module dependency for a sub-deployment within ear ?
