--------------------------------------------------------------
spark-1.5.2 on MacOS chokes on the following in the same way (and, so does 2.1.1 on Linux)
-------
import org.apache.spark.graphx.{Edge, Graph}
case class Attr(what: Int, ever: Int)
val V = 11
val E = 42
def rndVertex = (V * Math.random).toLong
val edges = sc.parallelize(Array.fill(E)(Edge(rndVertex, rndVertex, Attr(-1, 0))))
val g = Graph.fromEdges(edges, 0)
val h = Graph.fromEdges(edges, 0)
println(g.edges.subtract(h.edges).count)

I have no idea what stupidity causes the linebreak between '.' and '{' ...
