* The test checks up getAllClasses(), getLoadedClassCount(),
* getTotalLoadedClassCount(), getUnloadedClassCount() methods when 100
* classes are unloaded by 100 loaders, which are the instances of the
* same ClassLoader class.
* Access to the management metrics is accomplished through the MBeanServer.
* The unload011 test is performed for the ClassLoadingMBean interface under
* DEFAULT implementation of MBean server.
