Problem description:
Current implementation of Java Plugin expects the following order of plugin methods during initialization:
NPP_New - create new plugin instance
NPP_SetWindow - start an applet
NPP_GetValue(NPPVpluginScriptableNPObject) - create and return applet scrip object to the browser

Sometimes the invocations of NPP_SetWindow and NPP_GetValue may be swapped, (NPP_GetValue(NPPVpluginScriptableNPObject) is called before NPP_SetWindow). In this case Java Plugin creates 'namespace' script object instead of real applet object and returns it to the browser. As a result it is impossible to invoke applets methods via Java Script, since incorrect script object is used by the browser.
