S1ASJVMStatsImplMockpublic class S1ASJVMStatsImplMock extends Object implements S1ASJVMStatsMock| Mock class for using JVMStats as a component that will register and
unregister with a MonitoringRegistration object which in turn created a
dynamic MBean that will be registered with the MBeanServer using an ObjectName
that has a unique identifier. |
