InstantiationException: org.jboss.as.weld.webtier.jsf.WeldApplicationFactory when trying to use JSF 1.2 in JBoss EAP 6

Issue

• We are have an issue with deploying two wars with different jsf versions in an ear project. War one is jsf 1.2 and the second war is jsf 2.2. We are using jboss-deployment-structure.xml in the ear project to define the class loading. The stack trace we are getting is:

jboss-deployment-structure.xml
