> If a Service MBean is a Clustered HA Singleton (it extends HASingletonSupport, or it is run by HASingletonController) and it throws an Exception when stopping then it is impossible to redeploy that Service until the whole JBoss is restarted.
> Any attempts at deploying the Service will results in the following error
> 15:47:43,766 WARN  [ServiceController] Problem starting service hatest:service=MyHASingletonService
> java.lang.NullPointerException
>         at org.jboss.ha.jmx.HAServiceMBeanSupport.getServiceHAName(HAServiceMBeanSupport.java:361)
