* 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.
