| /** |
| * The test for the implementation of an object of the type <BR> |
| * EventSet. <BR> |
| * <BR> |
| * The test checks that results of the method <BR> |
| * <code>com.sun.jdi.EventSet.eventIterator()</code> <BR> |
| * complies with its spec. <BR> |
| * <BR> |
| * The test checks that for ThreadStartEvent and <BR> |
| * ThreadDeathEvent sets: <BR> |
| * - the method returns non-null object; <BR> |
| * - object's class is subclass of class Iterator. <BR> |
| * <BR> |
| * The test has three phases and works as follows. <BR> |
| * <BR> |
| * In first phase, <BR> |
| * upon launching debuggee's VM which will be suspended, <BR> |
| * a debugger waits for the VMStartEvent within a predefined <BR> |
| * time interval. If no the VMStartEvent received, the test is FAILED. <BR> |
| * Upon getting the VMStartEvent, it makes the request for debuggee's <BR> |
| * ClassPrepareEvent with SUSPEND_EVENT_THREAD, resumes the VM, <BR> |
| * and waits for the event within the predefined time interval. <BR> |
| * If no the ClassPrepareEvent received, the test is FAILED. <BR> |
| * Upon getting the ClassPrepareEvent, <BR> |
| * the debugger sets up the breakpoint with SUSPEND_EVENT_THREAD <BR> |
| * within debuggee's special methodForCommunication(). <BR> |
| * <BR> |
| * In second phase the debugger and the debuggee perform the following. <BR> |
| * - The debugger creates ThreadStartRequest,resumes the debuggee, and <BR> |
| * waits for corresponding ThreadStartEvent. <BR> |
| * - The debuggee starts new thread, named "thread2", <BR> |
| * whose running creates the needed events. <BR> |
| * - Upon getting the ThreadStartEvent, the debugger checks up on it, <BR> |
| * creates ThreadDeathRequest, resumes the debuggee, and <BR> |
| * waits for corresponding ThreadDeathEvent. <BR> |
| * Upon getting the ThreadDeathEvent, the debugger checks up on it. <BR> |
| * <BR> |
| * In third phase, the debugger and the debuggee end. <BR> |
| * <BR> |
