31  * Notification of target VM termination.
32  * This event occurs if the target VM terminates before the
33  * VM disconnects ({@link VMDisconnectEvent}).
34  * Thus, this event will NOT occur if
35  * external forces terminate the connection (e.g. a crash)
36  * or if the connection is intentionally terminated with
37  * {@link com.sun.jdi.VirtualMachine#dispose()
38  *      VirtualMachine.dispose()}
39  * <P>
40  * On VM termination, a single unsolicited VMDeathEvent
41  * will always be sent with a
42  * {@link com.sun.jdi.request.EventRequest#suspendPolicy() suspend policy}
43  * of {@link com.sun.jdi.request.EventRequest#SUSPEND_NONE SUSPEND_NONE}.
44  * Additional VMDeathEvents will be sent in the same event set if they are
45  * requested with a
46  * {@link com.sun.jdi.request.VMDeathRequest VMDeathRequest}.
47  * <P>
48  * The VM is still intact and can be queried at the point this
49  * event was initiated but immediately thereafter it is not
50  * considered intact and cannot be queried.
51  * Note: If the enclosing {@link EventSet} has a
52  * {@link com.sun.jdi.request.EventRequest#suspendPolicy() suspend policy}
53  * other than
54  * {@link com.sun.jdi.request.EventRequest#SUSPEND_ALL SUSPEND_ALL}
55  * the initiating point may be long past.
56  * <P>
57  * All VMDeathEvents will be in a single {@link EventSet},
58  * no other events will be in the event set.  A resume
59  * must occur to continue execution after any event set which
60  * performs suspensions - in this case to allow proper shutdown.
