+ * @summary converted from VM Testbase nsk/monitoring/stress/classload/load012.
+ * VM Testbase keywords: [stress, monitoring, nonconcurrent]
+ * VM Testbase readme:
+ * DESCRIPTION
+ *     The test checks up getAllClasses(), getLoadedClassCount(),
+ *     getTotalLoadedClassCount(), getUnloadedClassCount() methods when 100
+ *     classes are loaded by 100 loaders, which are the instances of the
+ *     same ClassLoader class.
+ *     Access to the management metrics is accomplished through the MBeanServer.
+ *     The load012 test is performed for the ClassLoadingMBean interface under
+ *     CUSTOM implementation of MBean server.
+ * COMMENTS
+ *     Fixed the bug
+ *     4976274 Regression: "OutOfMemoryError: Java heap space" when -XX:+UseParallelGC
