If SingletonStatelessSessionInstancePool is used for a SLSB, container MBean state is reported incorrectly
----------------------------------------------------------------------------------------------------------

                 Key: JBAS-5528
                 URL: http://jira.jboss.com/jira/browse/JBAS-5528
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: EJB2
    Affects Versions: JBossAS-4.0.5.GA
         Environment: JDK 1.4.2, Windows NT 5.1, Cygwin
(any other anvironment should do as well, though).
            Reporter: Andrew Shcheglov
         Assigned To: Alexey Loubyansky


If SingletonStatelessSessionInstancePool instead of regular StatelessSessionInstancePool is used for a SLSB,
State/StateString JMX attributes
of the container MBean (jboss.j2ee:jndiName=XXX,plugin=pool,service=EJB)
are always 8/Registered.

This is most probably caused by the fact that org.jboss.ejb.plugins.SingletonStatelessSessionInstancePool class
directly overrides create()/start()/stop()/destroy() operations
with empty implementations,
which any MBean derived from ServiceMBeanSupport shouldn't.

This seems even more useless
since AbstractInstancePool (the direct superclass of SingletonStatelessSessionInstancePool )
doesn't override any methods from ServiceMBeanSupport.
