Fixed in r1005860. After discussing with Benjamin, decided not to go for an IllegalArgumentException as it would not represent a clear error link to the user receiving it. Instead, the empty goal or overspecified goal (goal:toomany) are sent to the MojoNotFoundException so the user ends up getting back valid choices of goals from the plugin in question.
