 * This class is intended as a controller for the JPPF driver, to enable stopping and restarting it when requested.

It performs the following operations:
 * 

 * open a server socket the driver will listen to (port number is dynamically attributed)
 * Start the JPPF driver as a subprocess, sending the the server socket port number as an argument
 * Wait for the subprocess to exit
 * If the subprocess exit code is equal to 2, the subprocess is restarted
