It's not an easy fix - there are multiple bugs in the collecting-finish
construct.
I opened a JIRA so you can follow our progress.
As a work-around, use a reducer without generic parameters, e.g.,
class Adder {
static abstract class A implements Reducible[Int] {}
def test2(r:A) {
val x = finish (r) { offer 5;};
}
}
