Redeploy dependent ear/war fails with duplicate resource error for persistence unit in JBoss EAP 6.4

Solution Verified - Updated -

Issue

We have an EAR which depends on a WAR. If we undeploy the WAR and then redeploy it, an exception is thrown:

Caused by: java.lang.IllegalStateException: JBAS014666: Recurso duplicado incluso myear.ear/myejb.jar#perunit

EAR jboss-all.xml configuration:

    <jboss umlns="urn:jboss:1.0">
        <jboss-deployment-dependencies xmlns="urn:jboss:deployment-dependencies:1.0">
            <dependency name="mywar.war" />
        </jboss-deployment-dependencies>
    </jboss>
