The following new event is going to be added into the JVMTI for JDK 9:
  void JNICALL MonitorNotify(JvmtiEnv* env, JNIEnv* jni_env,
                                                jhread thread, jobject monitor, bool is_notify_all);

It is needed to associate the Monitor{Wait/Waited} events with the notify event.
It seems reasonable to have a matching event in the JDI/JDWP.

The package com.sun.jdi.event must be extended with the new interface:

 public interface MonitorNotifyEvent extends LocatableEvent

The interface should define the following three methods:

ThreadReference thread()

Returns the thread in which this event has occurred.

Specified by:
    thread in interface LocatableEvent
Returns:
    a ThreadReference which mirrors the event's thread in the target VM.


ObjectReference monitor()

Returns the monitor that was entered.

Returns:
    an ObjectReference for the monitor.


boolean isNotifyAll()

Returns whether the notify event was triggered by the NotifyAll().

Returns:
    true if the event was triggered by the NotifyAll().
