Behaviour of EJB Timers if a new version of an application is deployed in EAP6 or EAP7

Issue

• If a new version of an application is deployed we expect that the persistent timers are continued. But this is not the case, all previous active timers are lost.
• we have an application with name testapp-1.0.0-1.ear that is using ejb-timers. When we upgrade the application with a new version, we got problem with the persistence under the "data/timer-service-data"-directory. Because we have the version in both ear, and war-files, we got a lot of directorys under JBOSS_HOME/data/timer-service-data.
