| /** |
| * The test for the implementation of an object of the type <BR> |
| * ReferenceType. <BR> |
| * <BR> |
| * The test checks up that results of the method <BR> |
| * <code>com.sun.jdi.ReferenceType.nestedTypes()</code> <BR> |
| * complies with its spec. <BR> |
| * <BR> |
| * Cases for testing include ArrayType and primitive classes. <BR> |
| * <BR> |
| * The test works as follows. <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 <BR> |
| * for debuggee's ClassPrepareEvent with SUSPEND_EVENT_THREAD, <BR> |
| * resumes the VM, and waits for the event within the predefined<BR> |
| * time interval. 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> |
| * the debugger resumes the debuggee and waits for the BreakpointEvent. <BR> |
| * The debuggee prepares new check and invokes the methodForCommunication<BR> |
| * to be suspended and to inform the debugger with the event. <BR> |
| * Upon getting the BreakpointEvent, the debugger performs the check. <BR> |
| * At the end, the debuggee changes the value of the "instruction" <BR> |
| * to inform the debugger of checks finished, and both end. <BR> |
