This becomes an infinite loop when failed==transferCount
I modified the loop in this way and it seems to work:

while (finished < transferCount && transferCount != 0) {
        	if ((failed == transferCount) && (failed != 0)) {
                System.out.println( "All Transfers failed !");
                System.exit(-1);
            }
        	
        	Thread.sleep(1000);
        }

I've still not tested it when not all the transfers fail.
Maybe a simpler solution can work also for this case:

while (finished+failed < transferCount && transferCount != 0) {
        Thread.sleep(1000);
}
