* @summary converted from VM Testbase nsk/jdb/suspend/suspend001.
* VM Testbase keywords: [jpda, jdb]
* VM Testbase readme:
* DESCRIPTION
* A positive test case for the 'suspend <thread id>' command.
* The debugged application (suspend001a.java) creates two addional threads.
* First thead is of Suspended class, second one is of MyThread class.
* The jdb stops debuggee at a moment after addional thread have started and
* before their completion. Then jdb calls 'suspend' command with id of
* the Suspended thread and resumes debuggee. The suspended thread should
* not modify special int 'notSuspended' variable of the suspend001a class.
* The test passes if suspend001a.notSuspended variable equals to 1, i.e.
* only not-suspended MyThread thread had modified it.
* The test consists of two program:
* suspend001.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
* suspend001a.java - the debugged application.
* COMMENTS
