* @summary converted from VM Testbase nsk/jdb/threads/threads003.
* VM Testbase keywords: [jpda, jdb]
* VM Testbase readme:
* DECSRIPTION
* This is a test for jdb 'threads' command in conjunction with jdb's
* ability to start tracking a vthread when the first event arrives on it.
* It also tests that vthreads where no event is received are not tracked.
* The debugee starts 5 'MyThreads'. The odd numbered threads call a
* method that has been setup as a breakpoint. The others do not. All
* 5 are then suspended on a lock that the main thread posseses. The
* 'threads' command is issued at this point. The test passes if
* only 'MyThreads-1' and 'MyThreads-3' are reported.
*
