public class JmxClientStatResourcesCleanupDUnitTest
extends AdminDUnitTestCase

This is a DUnit test to verify clean up of client statistic JMX resources created in cache & application member VMs when a client gets disconnected.

 For testCleanUp:
 
 1. Start agent from current JMX client VM (VM#4) 
 2. From JMX client VM, invoke connectToSystem on agent VM. Collect reference
    to distributed system MBean in setUp. 
 3. Start the cache & initialize the system in cache VM (CACHE_VM i.e. VM#0).
 4. From JMX client VM, invoke manageSystemMemberApplications on distributed 
    system MBean (in step 2). On the SystemMember manageStat method is called 
    over JMX.
 5. Count number of JMX statistics resources. 
 6. Start & connect a cache client (CLIENT_VM i.e. VM#2) to the cache VM.   
 7. Invoke operation manageStat on the SystemMember. Count number of JMX 
    statistics resources.
 8. Stop the client & disconnect from the cacheVM.
 9. Invoke operation manageStat on the SystemMember. Count number of JMX 
    statistics resources, it should be same as in step 5.
    
 For testClientMembership: 
 1. Start agent from current JMX client VM (VM#4) 
 2. From JMX client VM, invoke connectToSystem on agent VM. Collect reference
    to distributed system MBean in setUp. 
 3. Start the cache & initialize the system in cache VM (CACHE_VM i.e. VM#0).
 4. From JMX client VM, invoke manageSystemMemberApplications on distributed 
    system MBean (in step 2). On the SystemMember manageStat method is called 
    over JMX. Register Notification Listener on this SystemMember MBean.
 5. Count number of Notifications. 
 6. Start & connect a cache client (CLIENT_VM i.e. VM#2) to the cache VM.   
 7. Invoke operation manageStat on the SystemMember. Count number 
    Notifications, it should be more than in step 5.
 8. Stop the client & disconnect from the cacheVM.
 9. Invoke operation manageStat on the SystemMember. Count number of JMX 
    Notifications, it should be more than in step 7.
