* Description:  This application is executed by the native installer
*               after a new version of Jrt has been installed from
*               .sisx package on top of older Jrt version (e.g. when
*               updating Jrt 2.1 to Jrt 2.2 via IAD).
*               This application restarts Java Captain so that new
*               version of the Jrt dlls is taken into use.
*               All running MIDlets exit when Java Captain closes.
