ehcache.xml needed for JBoss Deployment

[rpledger]

https://github.com/ozoneplatform/owf-framework/wiki/Running-OWF-in-JBoss should be updated to include ehcache.xml in standalone/deployments/owf.war/WEB-INF/classes.

For JBoss deployment of OWF 7.17.1 with ozone-security-3.28, ehcache.xml file in OWF-bundle-7.17.1/apache-tomcat/lib needs to be placed in standalone/deployments/owf.war/WEB-INF/classes otherwise it causes a NullPointerException in ozone/security/session/ClusteredSessionRegistryImpl.java when SessionManagementBeans.xml is included in OWFsecurityContext_cert_ldap.xml

Caused by: org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [ozone.security.session.ClusteredSessionRegistryImpl]: Constructor threw exception; nested exception is java.lang.NullPointerException
