  /**
   * Execute applet events. Here is the state transition diagram

   *  (applet code loaded) --> APPLET_LOAD -- (applet init called)--> APPLET_INIT --
   *  (applet start called) --> APPLET_START -- (applet stop called) --> APPLET_STOP --
   *  (applet destroyed called) --> APPLET_DESTROY --> (applet gets disposed) -->
   *   APPLET_DISPOSE --> ...
   * }</pre>
   *
   * In the legacy lifecycle model. The applet gets loaded, inited and started. So it stays in the
   * APPLET_START state unless the applet goes away(refresh page or leave the page). So the applet
   * stop method called and the applet enters APPLET_STOP state. Then if the applet is revisited, it
   * will call applet start method and enter the APPLET_START state and stay there.
   *
   * <p>In the modern lifecycle model. When the applet first time visited, it is same as legacy
   * lifecycle model. However, when the applet page goes away. It calls applet stop method and
   * enters APPLET_STOP state and then applet destroyed method gets called and enters APPLET_DESTROY
   * state.
   *
   * <p>This code is also called by AppletViewer. In AppletViewer "Restart" menu, the applet is jump
   * from APPLET_STOP to APPLET_DESTROY and to APPLET_INIT .
   *
   * <p>Also, the applet can jump from APPLET_INIT state to APPLET_DESTROY (in Netscape/Mozilla
   * case). Same as APPLET_LOAD to APPLET_DISPOSE since all of this are triggered by browser.
