This is a problem with the new interface impl logic.

thing.rb:
{noformat}
require 'java'

class Thing < java.util.ArrayList
  include java.lang.Runnable

  def initialize; super(); end

  def run; end
end

Java::Yabba.new.array_list= Thing.new
{noformat}

Yabba.java
{noformat}
import java.util.ArrayList;
public class Yabba {
  public void setArrayList(ArrayList r) {}
}
{noformat}

error:
