Just adding in here, dart isn't the Old Irish word for javelin, it would translate to ga. Dart is a catch-all term that classifies a bunch of weapons like the Plumbata, Atlatl or Kestros. So yes, the Kern used a variety of weapons as Bones states.

And also just to provide a source to verify their use of the bow, here we are:

1."... A kind of footman, slightly armed with a sword, a target [round shield] of wood, or a bow and sheaf of arrows with barbed heads, or else three darts, which they cast with a wonderful facility and nearness.."
