I know that inheritance stuff, but none (!) of them catches that 
strange exception either. You can ignore the loop()-method. It is 
not called as the application will never reach this statement, 
because it cannot, because it crashes already in the 
listen()-method in consequence of the exception that does not get 
caught by the try-catch block.
