@Tristan do we then have a corresponding JIRA in AS7?

> Affects JBossAS 7.1.0.Alpha2-SNAPSHOT (with HEAD == 5058aab).
> Currently it is not possible to specify e.g. eviction-executor attribute on <cache-container> element since it needs a scheduled executor to be defined in Threads susbystem like this
> <scheduled-thread-pool name="infinispan-eviction">
>      <max-threads count="1" per-cpu="0"/>
>      <thread-factory name="infinispan-factory"/>
> </scheduled-thread-pool>
> When I define this and start EDG (based on the JBossAS above), I get the following error:
> {code}

> The problem is that CacheContainerAdd.java is trying to add a Scheduled Executor dependency which is supposed to be of type ScheduledExecutorService.class. However, the Threads subsystem has recently changed (https://github.com/jbossas/jboss-as/commit/c803d7a4964554fdbe691f969f9766c8f7390d21#threads/src/main/java/org/jboss/as/threads/ScheduledThreadPoolAdd.java) and it creates a service builder of type ServiceBuilder<ManagedScheduledExecutorService> (see jboss-as/threads/src/main/java/org/jboss/as/threads/ScheduledThreadPoolAdd.java) 
> So I think it might be enough just to change the CacheContainerAdd.java to ask for ManagerScheduledExecutorService.class.
