 * @summary converted from VM Testbase nsk/jdb/threadgroup/threadgroup002.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DECSRIPTION
 *  This is a test for jdb 'threadgroup <threadgroup_name>' command and
 *  also for the 'threadgroup' command with no argument.
 *  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 test then makes sure jdb correctly switches between
 *  the three user-defined threadgroups using 'threadgroup' command. It then
 *  resets the current threadgroup back to the default top level threadgroup
 *  by using the 'threadgroup' command with no argument. It then tests that
 *  all 3 created threadgroups can be found in the 'threads' output.
 * COMMENTS
 *  This test functionally equals to nsk/jdb/threadgroup/threadgroup001
 *  test and replaces it.
 *
