The file server/production/deploy/cluster/ha-legacy-jboss-beans.xml has wrong syntax (the bean element has no starting tag, moreover not sure if it should be there at all, so I've removed all that stuff to start the production config successfully):

<!-- ==================================================================== -->
<!-- Distributed EJB2 entity cache invalidation -->
<!-- ==================================================================== -->

<!-- Partition used for group RPCs -->

<property name="HAPartition"><inject bean="HAPartition"/></property>
<property name="invalidationManager"><inject bean="jboss.cache:service=InvalidationManager"/></property>
<property name="bridgeName">DefaultJGBridge</property>

</bean>

Note that this was reported and fixed in EWP 5.0.0 (JBPAPP-3672).
