| Housekeeper | | public class Housekeeper (Code) | | This class performs housekeeping and cleanup tasks. There can only be one instance of
Housekeeper per Java runtime, therefore this class is implemented as a
'Singleton'.
It is VERY important to perform pre-shutdown cleanup operations through this class. Do NOT rely
on operations like deleteOnExit() shutdown hooks or finalize()for
cleanup. Because shutDown() uses System.exit() to terminate, these
methods will not work at all or will not work reliably.
