sqlline user authentication provides poor feedback on authentication

When authenticating with sqlline using the -n and -p flags, if you provide an incorrect user/name and password, instead of just failing with a bad user/pass type message, there is a whole page of java stack trace. This should be a simple trapped message, because for users setting up authentication, the stack trace may be overwhelming and they then think the setup is wrong rather than setup is correct and user/pass is incorrect.
