+ * @summary converted from VM Testbase nsk/jdb/threadgroups/threadgroups002.
+ * VM Testbase keywords: [jpda, jdb]
+ * VM Testbase readme:
+ * DECSRIPTION
+ *  This is a test for jdb 'threadgroups' command.
+ *  The main thread creates 3 threadgroups of 5 threads each.
+ *  All threads are locked in their 'run' method on a lock that the main
+ *  thread holds. The 'threadgroups' command is issued at this point.
+ *  The test passes if three user-defined threadgroups are reported.
+ * COMMENTS
+ *  This test functionally equals to nsk/jdb/threadgroups/threadgroups001
+ *  test and replaces it.
+ *
