 * @summary converted from VM Testbase nsk/monitoring/stress/classload/load005.

 * VM Testbase keywords: [stress, monitoring, nonconcurrent]

 * VM Testbase readme:

 * DESCRIPTION

 *     The test checks up getAllClasses(), getLoadedClassCount(),

 *     getTotalLoadedClassCount(), getUnloadedClassCount() methods when one

 *     class is loaded by 100 loaders, which are the instances of the same

 *     custom ClassLoader class.

 *     Access to the management metrics is accomplished through the MBeanServer.

 *     The load005 test is performed for the ClassLoadingMBean interface under

 *     DEFAULT implementation of MBean server.
