    14 * Description:  This application is executed by the native installer

    15 *               after a new version of Jrt has been installed from

    16 *               .sisx package on top of older Jrt version (e.g. when

    17 *               updating Jrt 2.1 to Jrt 2.2 via IAD).

    18 *               This application restarts Java Captain so that new

    19 *               version of the Jrt dlls is taken into use.

    20 *               All running MIDlets exit when Java Captain closes.
