find-plan does not catch the error when the name contains non alphanumeric character

[tayruxin]

When I attempt to find for a plan by entering find-plan --john, the app does not respond. When checking the terminal there seem to be an illegal argument exception that was not handled by the app. This was accounted in the find-friend command.

It is not rare for users to key in a non-alphanumeric character by accident.

Team's Response

While it does provide inconvenience to the users to have to clear their command, and retype a correct command before proceeding. We feel that it should only be of low severity due to the following reasons:

• It will not affect most users as most users will look at their friends (friend names must be alphanumeric) available first, then find-plan by the shown names, so the likelihood of searching --john is not as frequent.
• Keying in this command does not crash the application, and stop the user from proceeding to use this application. Just by clearing the command and typing other commands, the user can continue to use FriendBook, hence this problem does not make the application 'almost unusable' for the user.
