The source compiled successfully, but when I run the testcase via scala-test I get the stack trace below. However, if I comment out one of the method with a long param list, the application runs fine.

Here's the method signature

def update[A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T](ca: Schema#Table#Column[A], cb: Schema#Table#Column[B], cc: Schema#Table#Column[C], cd: Schema#Table#Column[D], ce: Schema#Table#Column[E], cf: Schema#Table#Column[F], cg: Schema#Table#Column[G], ch: Schema#Table#Column[H], ci: Schema#Table#Column[I], cj: Schema#Table#Column[J], ck: Schema#Table#Column[K], cl: Schema#Table#Column[L], cm: Schema#Table#Column[M], cn: Schema#Table#Column[N], co: Schema#Table#Column[O], cp: Schema#Table#Column[P], cq: Schema#Table#Column[Q], cr: Schema#Table#Column[R], cs: Schema#Table#Column[S], ct: Schema#Table#Column[T])(va: A, vb: B, vc: C, vd: D, ve: E, vf: F, vg: G, vh: H, vi: I, vj: J, vk: K, vl: L, vm: M, vn: N, vo: O, vp: P, vq: Q, vr: R, vs: S, vt: T)(where: String = null)(implicit session: DBSession) = { /*body removed*/ }
