[jboss-jira] [JBoss JIRA] (AS7-2513) Infinispan Subsystem cannot use ScheduledExecutor from Threads subsystem
Infinispan Subsystem cannot use ScheduledExecutor from Threads subsystem
------------------------------------------------------------------------
Key: AS7-2513
URL: https://issues.jboss.org/browse/AS7-2513
Project: Application Server 7
Issue Type: Bug
Components: Clustering
Reporter: Martin Gencur
Assignee: Paul Ferraro
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}

Services which failed to start:
service jboss.infinispan.default: org.jboss.msc.service.StartException in service
jboss.infinispan.default: Failed to start service
{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 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.
