Description: When holding shift while hovering your mouse over backpack upgrades in NEI to see more info, it displays as 'unknown', as can be seen in the Gyazo .gif linked below. When I hold shift and hover over one of the backpack upgrades while inside the NEI recipe display for it, I receive the client crash linked below.
(Sorry for having another bug again lol)

@gr8pefish You imported the wrong Arrays class. You want java.util.Arrays, not scala.actors.threadpool.Arrays

Fixed in 1.2.5

Amateur mistakes for days! Ugh :/
