Request for notification when a field is set.
This event will be triggered when a value is assigned to the specified
field with a JavaTM programming
language statement (assignment, increment, etc) or by a
Java Native Interface (JNI) set function (Set<Type>Field,
SetStatic<Type>Field). Setting a field to a value which is the same as the previous value still triggers this event. Modification by JDI does not trigger this event. When an enabled ModificationWatchpointRequest is satisfied, an event set containing a ModificationWatchpointEvent will be placed on the EventQueue. The collection of existing watchpoints is managed by the EventRequestManager.
