    Description

      EJB-Component is missing an integrated EJB-Timer-Implementation.

      Creating a time from within an EJB gives the following stacktrace:
      ...

      Caused by: java.lang.UnsupportedOperationException: This is a temporary non-functional timerservice. No operations are allowed on it.
        at org.jboss.as.ejb3.component.EJBComponent$NonFunctionalTimerService.<init>(EJBComponent.java:337)
        at org.jboss.as.ejb3.component.EJBComponent$NonFunctionalTimerService.<init>(EJBComponent.java:335)

        at org.jboss.as.ee.component.ManagedReferenceFieldInjectionInterceptor.processInvocation(ManagedReferenceFieldInjectionInterceptor.java:64)

      The problem is a missing piece in the EJBComponent.java(line 198): 

          public TimerService getTimerService() throws IllegalStateException {
        // TODO: Temporary, till we have a working timerservice integrated
        return new NonFunctionalTimerService();
    }
