Request for notification when the contents of a field are accessed
in the target VM.
This event will be triggered when the specified field is accessed
by Java™ programming language code or by a
Java Native Interface (JNI) get function (Get<Type>Field,
GetStatic<Type>Field). Access by JDI does not trigger this event. When an enabled AccessWatchpointRequest is satisfied, an event set containing an AccessWatchpointEvent will be placed on the EventQueue. The collection of existing ExceptionRequests is managed by the EventRequestManager The collection of existing watchpoints is managed by the EventRequestManager. 

Note that the modification
of a Field is not considered an access.
