34   * language statement (assignment, increment, etc) or by a
35   * Java Native Interface (JNI) set function (<code>Set&lt;Type&gt;Field,

37   * Setting a field to a value which is the same as the previous value
38   * still triggers this event.
39   * Modification by JDI does not trigger this event.
