Galder Zamarreno commented on JBAS-5471:
----------------------------------------

After injecting the mbeanServer in the kernelAbstraction, I got:

18:26:22,985 ERROR [STDERR] Caused by: java.lang.RuntimeException: java.lang.NullPointerException
18:26:22,986 ERROR [STDERR]     at org.jboss.ejb3.deployers.JBossASKernel.installMBean(JBossASKernel.java:149)
18:26:22,990 ERROR [STDERR]     at org.jboss.ejb3.service.ServiceContainer.registerManagementInterface(ServiceContainer.java:587)

Is there any need to call:

   public void installMBean(ObjectName on, DependencyPolicy dependencies,
         Object service)
   {
      if(mbeanServer == null)
         throw new RuntimeException("No MBeanServer has been injected");

      try
      {
         mbeanServer.registerMBean(service, on);        
         install(on.getCanonicalName(), dependencies, null, service);

Judging from the log just before the exception:

18:26:20,829 INFO  [JBossASKernel] installing bean: jboss.j2ee:jar=acme-ejb3-service.jar,name=SystemTimeService,service=EJB3
18:26:20,830 INFO  [JBossASKernel]   with dependencies:
18:26:20,830 INFO  [JBossASKernel]   and demands:
18:26:20,830 INFO  [JBossASKernel]      jboss.ejb:service=EJBTimerService
18:26:20,830 INFO  [JBossASKernel]   and supplies:
18:26:20,831 INFO  [JBossASKernel]      Class:com.acme.ejb3.service.Time
18:26:22,203 INFO  [EJBContainer] STARTED EJB: com.acme.ejb3.as5.service.SystemTimeService ejbName: SystemTimeService

The bean itself has already been installed in the MC, so installMBean 
should only need to make sure that it's registered properly with the mbean 
server. I don't think there's a need to call install() again. I'll try this and see
what happens.

> I'll have a go at passing the mbeanServer to the kernelAbstraction and see if that fixes it.
