When the hooks parameter is null, the application instance will be used if it implements VertxApplicationHooks.

Parameters:

args - the program arguments

hooks - an instance of VertxApplicationHooks to be invoked at different stages of the launch process (maybe null)

printUsageOnFailure - whether usage should be printed to System.out if the application failed to start
